fix: audit fixes — shellcheck, TTY signcolumn, matchdelete race, docs accuracy

- install.sh: ls -A → find (shellcheck SC2012)
- navigation.vim: GFiles -nargs=? to support :GFiles?
- lsp.vim: signcolumn=yes gated behind !g:is_tty
- editing.vim: matchdelete in timer wrapped with silent!
- README: gofmt → goimports, plugin count 24–25
- CHANGELOG: annotate removed features (ChopsticksLearn, vim . layout)
