Make PlugClean interactive in install.sh

Previously install.sh ran `_vim_run 'PlugClean!'` unconditionally before
PlugInstall. PlugClean with bang removes any directory under
~/.vim/plugged not declared in the active profile's g:plugs, without
confirmation — silently nuking plugins a user has manually cloned to try
out, plus leftovers from older profile config (Goyo, Limelight, etc.).

Replace with a `list_extra_plugins` helper that runs a Vim subprocess
with all opt-in flags forced on and `$TMUX = '1'`, so the declared set
covers every plugin any chopsticks profile/flag combination could
register. Conditional plugins (vim-tmux-navigator, auto-pairs) are
therefore never flagged as extras.

When extras are detected:
- interactive: list them, ask before running PlugClean!
- --yes: leave in place, instruct the user to run :PlugClean manually
- otherwise (no extras): skip PlugClean entirely (saves an 80ms Vim
  launch on the common case)

Closes #64

 ### Fixed
 
+- `install.sh` no longer silently `PlugClean!`s user-added plugins from
+  `~/.vim/plugged`; it now lists undeclared plugin directories first and
+  asks before removing them (`--yes` skips the removal entirely)
 - `g:loaded_logipat` typo → `g:loaded_logiPat` — logiPat was loading fully (0.478ms wasted)
 - `get.sh` now refuses to update an existing `~/.vim` git repo unless its
   origin is chopsticks

 ### Changed
 
+- `set exrc`/`set secure` are now opt-in via `g:chopsticks_enable_exrc = 1`;
+  Vim no longer sources project-local `.vimrc`/`.exrc` from the working
+  directory by default
+- Normal-mode `,F` (reindent the entire file with `gg=G`) is now opt-in
+  via `g:chopsticks_enable_reindent_file = 1`; visual-mode `,F` (reindent
+  selection) stays as the default since it's bounded by the user's pick
 - `,?` cheat sheet is now profile-aware and hides LSP/ALE/preview/UndoTree keys
   when those features are disabled
 - Module reload/source paths now use `fnameescape()` so installs in paths with

 ## Rules
 
-1. **No Node.js dependencies.** The LSP engine is pure VimScript. Some language servers need Node — that's fine. The config itself must not.
+1. **No Node.js in the Vim runtime.** Plugins must work with pure VimScript — no coc.nvim or other Node-backed completion engines. External CLIs (prettier, eslint, markdownlint, stylelint, tsc) installed via npm are fine; ALE shells out to them as optional system tools, not as part of the Vim runtime.
 2. **Startup matters.** Run `vim -u .vimrc -i NONE --startuptime /tmp/s.log -es -N -c qa!` before and after. If your change adds >1ms, it needs a good reason.
 3. **Works on TTY.** Test over SSH. If it breaks in a terminal without true color, fix it or gate it behind `g:is_tty`.
 4. **Native-first keymaps.** Enhance Vim's native behavior instead of replacing it. Do not override built-in motions, operators, text objects, or help-oriented keys for discoverability alone; prefer leader-prefixed or otherwise non-conflicting ergonomic mappings.
