[1.2.4] - 2026-03-04

Added

• 履歴ウィンドウで Del キーによる削除: コマンド履歴セレクター（Ctrl+R）で
  選択中のエントリを Del キーで削除できるようになった。削除後はリストが即座に
  更新され、カーソル位置は維持される（最終行を削除した場合は一つ上に移動）。
  削除はファイルにも即座に反映される。

• ヒントバー表示を更新: Enter:Run Del:Delete S-Enter:&& Esc:Close

• Shell integration (OSC 133 / OSC 633) for accurate command history:

  • VT parser now recognises OSC 133 and OSC 633 (VS Code extension) markers
    emitted by PowerShell, bash, zsh, fish, oh-my-posh, and Starship.
  • Marker B records the exact cursor column where user input begins, making
    history capture independent of prompt appearance (no more strip_prompt
    regex for modern shells).
  • Marker C captures the confirmed command text at the moment Enter is pressed.
  • Marker D records the exit code of the last command.
  • ShellIntegration struct added to TerminalState.

• Keystroke tracker (KeystrokeTracker) as a fallback for cmd.exe:

  • Intercepts every printable key before forwarding to the PTY.
  • Handles Backspace, Ctrl+W (delete word), Ctrl+U / Ctrl+C (clear line).
  • Active only when no OSC markers have been seen for the current pane.

• Tiered get_current_line() in WindowManager:

  • Priority 1: OSC confirmed command (marker C).
  • Priority 2: OSC prompt-end position (marker B) + screen buffer slice.
  • Priority 3: Keystroke tracker buffer.
  • Priority 4: Legacy strip_prompt heuristic (last resort).

• README: new Shell Integration section with setup instructions for
  PowerShell, bash/zsh (WSL), oh-my-posh, and cmd.exe fallback.

• Font configuration ([font] section in config.toml):

  • family — font family name (e.g. "Cascadia Code", "JetBrains Mono").
    Leave empty to inherit the host terminal's current font.
  • size — font size in points (0 = inherit from host terminal).
  • bold — force bold rendering for all text (default: false).
  • ligatures — enable ligatures for supported fonts (default: true).
  • Settings are applied at startup via OSC 50 escape sequences where the
    host terminal supports them (silently ignored otherwise).
  • config.example.toml updated with the new [font] section and examples.

Performance

• Dirty-line rendering: WmRenderer now skips rows that have not changed
  since the last frame. Only rows marked dirty by the VT parser are redrawn,
  cutting render work to near-zero for idle panes (e.g. a vim split next to a
  running build log).
• Per-pane output tracking: panes that produced no new output since the
  last render pass are skipped entirely, not just their unchanged rows.
• Batched SGR escape sequences: apply_attrs and apply_attrs_with_selection
  now emit a single \x1b[...m sequence per attribute group instead of one
  execute!() call per attribute. Reduces write call overhead by 5–10x per
  styled cell group.
• Resize debounce (30 ms): rapid terminal-resize events (fired every pixel
  during drag on Windows) are coalesced into a single resize + redraw after
  the window settles, eliminating flicker and redundant PTY resizes.
• clear_all_dirty() after render: dirty-line sets are now cleared after
  every render pass so subsequent frames start with a clean slate.
