Summary

  • Tree-sitter upgrade from 0.20 to 0.24 with all grammar crates updated
  • YAML and HTML syntax highlighting added (17 languages total)
  • TUI fixes — tab rendering (literal tab expansion, visual-column positioning), activity bar icon readability, C# grammar query updates
  • VSCode Mode Gap Closure — ~20 missing shortcuts across 3 phases (Alt key routing, line operations, multi-cursor Ctrl+D/Ctrl+Shift+L, indentation, panel toggles, quick navigation, Ctrl+K chord prefix)
  • Extensions UX overhaul — Enter shows README preview, i key installs, all 16 extension READMEs rewritten, new EXTENSIONS.md development guide, commentary Lua extension removed (native :Comment replaces it)
  • Terminal-based extension install — install scripts run in a visible terminal pane (real-time output, sudo support, exit status display) instead of silently in the background
  • F1 command palette — opens Command Palette in both Vim and VSCode modes (fixes Ctrl+Shift+P not working in many terminals)
  • Word-boundary wrapping — compute_word_wrap_segments() in render.rs
  • Workspace session isolation — global session open_files cleared to prevent cross-workspace bleed
  • LSP kickstart after extension install — lsp_did_open called on active buffer after install completes

Test plan

  • All 3995 tests pass
  • cargo clippy -- -D warnings clean
  • cargo fmt --check clean
  • cargo build succeeds

feat: VSCode mode gap closure phases 1–3, 55 tests
791c596 
Phase 1 — Line Operations + Alt Key Routing:
Alt encoding in TUI/GTK backends for VSCode mode (Alt+key → "Alt_Up" etc.),
Alt+Up/Down move line, Alt+Shift+Up/Down duplicate line, Ctrl+Shift+K delete
line, Ctrl+Enter/Ctrl+Shift+Enter insert blank line, Ctrl+L select line.

Phase 2 — Multi-Cursor + Indentation:
Ctrl+D progressive word select with extra cursors at next occurrence,
Ctrl+Shift+L select all occurrences (new vscode_select_all_occurrences()),
multi-cursor typing/backspace using char-index descending sort for same-line
correctness, extra selections rendering in both backends, Ctrl+]/[ indent/
outdent with multi-cursor support, Shift+Tab outdent.

Phase 3 — Panels + Quick Navigation:
Ctrl+G go to line (with ensure_cursor_visible), Ctrl+P fuzzy finder,
Ctrl+Shift+P command palette, Ctrl+B toggle sidebar, Ctrl+J/Ctrl+` toggle
terminal (returns EngineAction::OpenTerminal), Ctrl+, settings, Ctrl+K
chord prefix.

Bug fixes:
- GTK terminal panel mouse off-by-one (term_px +1→+2 for tab bar row)
- GTK terminal + button not working (toolbar row misidentified)
- :N go-to-line not scrolling (missing ensure_cursor_visible)

UI polish:
- Bottom panel tab bar uses sans-serif UI_FONT with uppercase labels
- Terminal toolbar uses sans-serif font matching VSCode style

….3.2

Upgrade tree-sitter stack from 0.20 to 0.24 with all grammar crates.
Add YAML and HTML syntax highlighting (17 languages total). Fix YAML
key/value color distinction, TUI tab rendering (expand tabs to spaces),
and TUI activity bar icon readability (off-white + accent bar).

…verhaul

Extension install scripts now run in a visible terminal pane instead of
silently in the background — users see real-time output, errors, and can
enter sudo passwords. F1 opens Command Palette in both Vim and VSCode
modes (fixes Ctrl+Shift+P not working in many terminals). Extensions UX:
Enter shows README preview, 'i' installs, word-boundary wrapping, workspace
session isolation fix, LSP kickstart after install, commentary extension
removed (native :Comment replaces it), all extension READMEs rewritten,
EXTENSIONS.md development guide. 3995 tests.

fix: bulk paste in insert mode — eliminate per-char reparse freeze
9bd0f3f 
Pasting large text in insert mode caused 100% CPU / UI freeze because
each character was fed through handle_key() individually, triggering
tree-sitter reparse + bracket match + auto-completion per character.

New Engine::paste_in_insert_mode() does a single insert_with_undo()
and runs expensive post-processing once. Also adds safety guard in
compute_word_wrap_segments() to prevent potential infinite loops.
