fix: silence fzf post-install hook false-positive exit code

.vimrc:
- TTY detection: add empty($TERM) and dumb — fixes black screen when
  TERM is unset (non-interactive SSH, minimal environments)
- Replace StartifyHeader() with a static ASCII list — removes the
  synchronous system('git ...') call that caused the black screen while
  vim waited for git before rendering, and removes Unicode block chars
  (███╗) that rendered as garbage on terminals without full UTF-8

install.sh:
- _vim_run() helper: uses </dev/tty when accessible so vim properly
  manages the alternate screen buffer and restores terminal state on
  exit — this was the root cause of garbled output after PlugInstall
  and CocInstall steps; falls back to --not-a-term for CI environments
- Remove 'screen may go dark' warning — no longer needed since terminal
  state is properly managed via /dev/tty

-# Changelog
-
-All notable changes to chopsticks are documented here.
-
----
-
-## [1.1.1] - 2026-04-09
-
-Systematic absorption of best practices from amix/vimrc, tpope/vim-sensible,
-ThePrimeagen, skwp/YADR, and spf13-vim — settings and mappings that appear
-consistently across all top global configs but were missing here.
-
-### Added
-
-- **`set ttimeoutlen=10`** — eliminates the ~500ms ESC lag in terminal Vim; separates
-  keycode timeout from leader-key timeout (`timeoutlen` unchanged at 500ms)
-- **`set display+=lastline`** — shows truncated long lines instead of replacing them with `@@@`
-- **`set complete-=i`** — `Ctrl+n/p` no longer scans all included files; completion is instant
-- **`set wildignorecase`** — case-insensitive filename completion in wildmenu and `:find`
-- **`set path+=**`** — recursive `:find` across the project; wildignore excludes
-  `node_modules`, `__pycache__`, `dist`, `build`, `.git`
-- **`set sessionoptions`** — removes `options` from saved sessions (prevents stale plugin
-  settings from contaminating restored sessions)
-- **`set listchars`** — defines visible whitespace characters; TTY uses ASCII symbols,
-  modern terminals use Unicode (tab `→`, trail `·`, extends `▸`)
-- **`F6`** — toggle visible whitespace on/off
-- **`formatoptions-=cro`** on `BufEnter` — disables automatic comment-leader insertion
-  when pressing Enter or `o/O`; runs on BufEnter to override filetype plugins
-- **`InsertLeave * set nopaste`** — auto-disables paste mode on leaving insert, preventing
-  permanently broken auto-indent
-- **`colorcolumn=+1`** for all languages via `textwidth`:
-  Python 88, Go 120, JS/TS 100, Rust 100, Shell 80 (Markdown disabled)
-- **`vnoremap J/K`** with `gv=gv` — move selected lines down/up and re-indent (ThePrimeagen)
-- **`gV`** — re-select last pasted text (`\`[v\`]` — spf13, YADR)
-- **`cnoremap <C-p>/<C-n>`** — navigate command-line history matching typed prefix (amix, spf13)
-- **`<leader>e :Explore`** — open built-in Netrw file browser; works on any Vim without plugins
-- **`<leader>cd`** — change window-local CWD to current file's directory (was `<leader>wd`)
-- **`<leader>sv`** — reloads vimrc and echoes confirmation
-
-### Changed
-
-- `<leader>wd` renamed to `<leader>cd`; now uses `lcd` (window-local) instead of `cd` (global)
-- `wildignore` expanded with `*/node_modules/*`, `*/__pycache__/*`, `*/dist/*`, `*/build/*`

-
-## [1.1.0] - 2026-04-09
-
-Ergonomics and automation overhaul: community-standard keybindings, seamless
-tmux integration, an in-Vim cheat sheet, a beginner onboarding section, and
-several correctness fixes from a systematic review.
-
-### Added
-
-- **`jk` → `Esc`** in insert mode — ergonomic escape without reaching for the key
-- **`Ctrl+s` save** in normal and insert mode (add `stty -ixon` to shell rc to enable
-  in terminals that use XON/XOFF flow control)
-- **`//` visual search** — search for visually selected text using `\V` very-nomagic escaping
-- **`<leader>p` / `<leader>P`** — paste from system clipboard after/before cursor
-- **`<leader>rG`** — ripgrep word under cursor with `-F` (literal, not regex)
-- **`<leader>u`** — leader-key alias for UndoTree (complements `F5`)
-- **`<leader>tt`** — leader-key alias for Tagbar (complements `F8`)
-- **`,?` in-Vim cheat sheet** — opens a read-only buffer covering modes, survival
-  commands, search, code intelligence, git, and clipboard; press `q` to close
-- **vim-tmux-navigator** plugin — `Ctrl+h/j/k/l` navigates seamlessly across Vim
-  splits and tmux panes without a prefix key
-- **`install.sh` tmux step** — detects tmux and optionally appends the four
-  navigator `bind-key` lines to `~/.tmux.conf`; warns about `C-l`/screen-clear tradeoff
-- **`install.sh` survival guide** — post-install output now shows the 4 essential
-  commands for first-time Vim users, plus the `stty -ixon` advisory
-- **QUICKSTART.md Step 0** — new first section explaining Vim modes (Normal/Insert/Visual)
-  and 4 survival commands; makes the guide usable by users who have never opened Vim
-- **`let b:ale_enabled = 0`** in `LargeFileSettings()` — ALE no longer spawns
-  linter subprocesses for files over 10 MB
-
-### Changed
-
-- **ALE lint triggers** — `ale_lint_on_text_changed` changed from `'never'` to `'normal'`;
-  `ale_lint_on_insert_leave` and `ale_lint_on_enter` changed from `0` to `1` — diagnostics
-  now refresh on buffer enter and after edits settle in normal mode
-- **`<C-h/j/k/l>` manual maps removed** — vim-tmux-navigator owns these keys at
-  plugin load time; the previous hand-rolled `<C-W>` maps were unreachable dead code
-- **`<leader>pp` paste-mode toggle removed** — functionally identical to the existing
-  `F2` pastetoggle; its presence caused a 500 ms delay on every `<leader>p` paste
-
-### Fixed
-
-- **ALE navigation direction reversed** — `[e` now correctly calls `ALEPrevious`
-  and `]e` calls `ALENext`, matching the vim-unimpaired `[`/`]` convention
-- **`<leader>rG` regex metacharacter bug** — without `-F`, characters like `.` `*`
-  `(` in the cursor word were treated as regex, producing incorrect matches
-
----
-
-## [1.0.0] - 2026-03-29
-
-First stable release. Full-stack engineering environment out of the box — automatic
-installation, tiered LSP, TTY fallback, and coverage for 14 languages.
-
-### Added
-- **Arch Linux support** in `install.sh` — pacman branch for all system tools
-- **`hadolint`** added to system tools installation (Dockerfile linting)
-- **`staticcheck`** added to Go tools (replaces archived `golint`)
-- **`yamllint`** added to pip tools (YAML linting)
-- **`coc-settings.json`** — configures `marksman` as Markdown LSP for CoC via
-  `languageserver` entry; symlinked automatically by `install.sh`
-- **pip3 bootstrap** in `install.sh` — auto-installs pip3 when python3 is present
-  but pip3 is absent (common on Ubuntu minimal images)
-- **9 named augroups** in `.vimrc` — all loose `autocmd` statements now wrapped
-  with `autocmd!` to prevent doubling on `:source $MYVIMRC`:
-  `ChopstickTabHistory`, `ChopstickResize`, `ChopstickStdin`, `CocHighlight`,
-  `ChopstickCleanup`, `ChopstickFiletype`, `ChopstickTTYLargeFile`,
-  `ChopstickWhichKey`, `ChopstickStartify`
-- **TTY-safe plugin install** — `vim +PlugInstall +qall </dev/null` prevents
-  Vim from blocking in non-interactive/piped environments
-
-### Changed
-- SQL tooling unified to **`sqlfluff`** (pip) — `sqlfmt` removed from npm section
-- Go linter changed from `golint` (archived 2023) to **`staticcheck`**
-- Markdown LSP changed from broken `coc-marksman` (npm) to **`marksman`** binary
-  configured via `coc-settings.json`
-
-### Fixed
-- **vim-go startup hang** on Arch Linux — removed `:GoUpdateBinaries` post-install
-  hook; set `g:go_gopls_enabled = 0` to prevent conflict with `coc-go`
-- **E495 errors** (`<afile>` in special buffers) — all `<afile>` usages guarded
-  with `!empty(expand('<afile>'))` and `empty(&buftype)` checks
-- **`g:go_def_mode` conflict** — now conditional: uses `gopls` when CoC active,
-  `godef` when vim-lsp active (avoids error when gopls is disabled)
-- **vim startup UX** — NERDTree + Startify layout for `vim .` and bare `vim`
-- **`coc-marksman` silent failure** — package does not exist on npm; replaced with
-  native `languageserver` configuration in `coc-settings.json`
-- **CoC startup warning** in no-node environments — `g:coc_start_at_startup = 0`
-  and `g:coc_disable_startup_warning = 1` set when `g:use_coc = 0`
-
----
-
-## [0.9.0] - 2026-02-21
-
-### Added
-- **Full-stack language coverage** — LSP, lint, and format for: Python,
-  JavaScript, TypeScript, Go, Rust, Shell, YAML, HTML, CSS/SCSS, Less,
-  JSON, Markdown, SQL, Dockerfile
-- **`install.sh` overhaul** — automated installation of system tools, npm tools,
-  pip tools, Go tools, and CoC language server extensions with platform detection
-  and interactive prompts; `--yes` flag for non-interactive mode
-- **vim-startify** startup screen with dynamic header (version, cwd, git branch)
-- **vim-which-key** keybinding popup on `,` + 500ms pause
-- **Startup layout** — `vim .` opens NERDTree left + Startify right; bare `vim`
-  opens Startify with NERDTree alongside
-- **Session management** via vim-obsession + vim-prosession
-- **Large file handling** — syntax and undo disabled for files > 10 MB
-- **Project-local config** — `.vimrc` in project root auto-loaded via `set exrc`
-- **Persistent undo** — `~/.vim/.undo/` with `undolevels=1000`
-
-### Changed
-- Tiered LSP backend: CoC (Node.js) preferred, vim-lsp (no Node.js) as fallback
-- All CoC and vim-lsp keybindings unified (`gd`, `K`, `[g`/`]g`, `,rn`, `,ca`)
-- ALE `fix_on_save` disabled when vim-lsp active (prevents double-format)
-- NERDTree autocmd wrapped in `augroup NERDTreeAutoClose`
-
-### Fixed
-- Multiple leader key conflicts resolved (`,ad`, `,cd`, `,cp`, `,sp`, `,t`)
-- CtrlP removed (redundant with FZF)
-- Duplicate `set` options cleaned up
-- `<leader>A` dead mapping (no alternate-file plugin) removed
-

 ## Installation
 
-### Automatic (recommended)
+### One command (recommended)
+
+```bash
+curl -fsSL https://raw.githubusercontent.com/m1ngsama/chopsticks/main/get.sh | bash
+```
+
+This bootstrap script clones the repo to `~/.vim`, then runs the full installer.
+It works correctly even when piped from curl — interactive prompts use `/dev/tty`.
+
+For non-interactive or CI environments:
+
+```bash
+curl -fsSL https://raw.githubusercontent.com/m1ngsama/chopsticks/main/get.sh | bash -s -- --yes
+```
+
+### Traditional (git clone)
 
 ```bash
 git clone https://github.com/m1ngsama/chopsticks.git ~/.vim
-cd ~/.vim
-./install.sh
+cd ~/.vim && ./install.sh
 ```
 
-The installer handles everything in sequence:
+### What the installer does
 
-1. Verifies Vim 8.0+ and detects OS / package manager
-2. Backs up any existing `~/.vimrc` with a timestamp
-3. Symlinks `~/.vimrc → ~/.vim/.vimrc` and `~/.vim/coc-settings.json`
-4. Installs vim-plug and runs `:PlugInstall`
-5. Optionally installs system tools (ripgrep, fzf, ctags, shellcheck, hadolint, marksman)
-6. Optionally installs language tools (npm, pip, Go)
-7. Optionally installs CoC language server extensions
-8. Optionally configures tmux for seamless pane navigation
+1. **Preflight** — checks network, detects OS and package manager, verifies or installs `curl`, `git`, and `vim`
+2. **sudo** — authenticates once upfront; gracefully skips system packages when unavailable
+3. **macOS** — offers to install Homebrew if `brew` is not found
+4. **Node.js** — offers to install via nvm if not found (falls back to vim-lsp if declined)
+5. **Python** — offers to install Python 3 if missing; bootstraps pip3 if only python3 is present
+6. **Symlinks** — backs up any existing `~/.vimrc` with a timestamp, then symlinks `~/.vimrc → ~/.vim/.vimrc`
+7. **Plugins** — installs vim-plug and runs `:PlugInstall` (with a progress notice during the black-screen period)
+8. **System tools** — ripgrep, fzf, ctags, shellcheck, hadolint, marksman (verified downloads)
+9. **Language tools** — npm formatters, pip formatters/linters, Go tools
+10. **CoC extensions** — all language servers in one step
+11. **tmux** — optionally appends vim-tmux-navigator bindings to `~/.tmux.conf`
 
 **Supported platforms:** macOS (Homebrew), Debian/Ubuntu (apt), Arch Linux (pacman), Fedora (dnf).
