a686f61c1d feat(tui): improve editor Ctrl/Alt word and line deletion shortcuts
- Add Ctrl+W for word deletion (stops at whitespace/punctuation)
- Add Ctrl+U for delete to start of line (merges with previous line at col 0)
- Change Ctrl+K from delete entire line to delete to end of line (merges with next line at EOL)
- Add Option+Backspace support in Ghostty (maps to Ctrl+W via ESC+DEL sequence)
- Cmd+Backspace in Ghostty works as Ctrl+U (terminal sends same control code)
- Update README and CHANGELOG with new keyboard shortcuts

Fixes #2, Fixes #3

02a21dd936 Fix viewport width issues in thinking selector and text rendering
Thinking selector fix:
- Replace hardcoded 50-character borders with DynamicBorder component
  that adjusts to viewport width
- Prevents crash when terminal is resized narrow

Text/Markdown rendering fixes:
- Fix Markdown wrapSingleLine to check if adding next character would
  exceed width BEFORE adding it (was checking AFTER, causing lines to
  be 1 character too long)
- Add word truncation in Text component for words longer than
  contentWidth (prevents long unbreakable words from exceeding width)

These fixes prevent "Rendered line exceeds terminal width" errors.

a3b3849188 Fix SelectList crash on narrow terminal and thinking level restoration
SelectList fixes:
- Use hardcoded visual width for arrow prefix instead of string length
  which includes ANSI codes
- Truncate scroll indicator text to prevent exceeding terminal width
- Fixes crash when terminal is resized narrow and arrow keys are pressed

Thinking level fix:
- Restore thinking level even if it's "off" (removed !== "off" check)
- This ensures the thinking level selector shows the correct state on continue

001beff394 Fix tab rendering in TUI components
Replace tabs with 3 spaces for consistent rendering and width calculation:
- Updated visibleWidth() to normalize tabs before measuring
- Updated Text and Markdown components to replace tabs when rendering
- Updated tool-execution display for read/write tools to replace tabs

This fixes background color rendering issues when displaying files with tab indentation.

741add4411 Refactor TUI into proper components
- Create UserMessageComponent - handles user messages with spacing
- Create AssistantMessageComponent - handles complete assistant messages
- Create ThinkingSelectorComponent - wraps selector with borders
- Add setSelectedIndex to SelectList for preselecting current level
- Simplify tui-renderer by using dedicated components
- Much cleaner architecture - each message type is now a component

dc1e2f928b Add /thinking command and improve TUI UX
- Add /thinking slash command with autocomplete for setting reasoning levels (off, minimal, low, medium, high)
- Fix Ctrl+C behavior: remove hardcoded exit in TUI, let focused component handle it
- Add empty lines before and after tool execution components for better visual separation
- Fix stats rendering: display stats AFTER tool executions complete (matches web-ui behavior)
- Remove "Press Ctrl+C again to exit" message, show "(esc to interrupt)" in loader instead
- Add bash tool abort signal support with immediate SIGKILL on interrupt
- Make Text and Markdown components return empty arrays when no actual text content
- Add setCustomBgRgb() method to Markdown for dynamic background colors

- Fixed wrapLine() to split by newlines before wrapping (like Text component)
- Fixed Loader interval leak by stopping before container removal
- Changed loader message from 'Loading...' to 'Working...'

- Remove old test files, keep only chat-simple.ts and virtual-terminal.ts
- Update README.md with new minimal API documentation
- Switch from tsc to tsgo for type checking
- Update package dependencies across monorepo

e21a46e68f feat(agent): Add /tokens command for cumulative token usage tracking
Added /tokens slash command to TUI that displays session-wide token statistics.
Key changes:
- Fixed SessionManager to accumulate token usage instead of storing only last event
- Added cumulative token tracking to TUI renderer alongside per-request totals
- Implemented slash command infrastructure with /tokens autocomplete support
- Fixed file autocompletion that was missing from Tab key handling
- Clean minimal display format showing input/output/reasoning/cache/tool counts

The /tokens command shows:
Total usage
   input: 1,234
   output: 567
   reasoning: 89
   cache read: 100
   cache write: 50
   tool calls: 2

6e40c5d761 fix(tui): Fix garbled output when content exceeds viewport
- Implemented new renderLineBased method that properly handles scrollback boundaries
- Fixed ANSI code preservation in MarkdownComponent line wrapping
- Added comprehensive test to reproduce and verify the fix
- Root cause: PARTIAL rendering strategy couldn't position cursor in scrollback
- Solution: Component-agnostic line comparison with proper viewport boundary handling

192d8d2600 fix(tui): Container change detection for proper differential rendering
Fixed rendering artifact where duplicate bottom borders appeared when components
dynamically shifted positions (e.g., Ctrl+C in agent clearing status container).

Root cause: Container wasn't reporting as "changed" when cleared (0 children),
causing differential renderer to skip re-rendering that area.

Solution: Container now tracks previousChildCount and reports changed when
child count changes, ensuring proper re-rendering when containers are cleared.

- Added comprehensive test reproducing the layout shift artifact
- Fixed Container to track and report child count changes
- All tests pass including new layout shift artifact test

afa807b200 tui-double-buffer: Implement smart differential rendering with terminal abstraction
- Create Terminal interface abstracting stdin/stdout operations for dependency injection
- Implement ProcessTerminal for production use with process.stdin/stdout
- Implement VirtualTerminal using @xterm/headless for accurate terminal emulation in tests
- Fix TypeScript imports for @xterm/headless module
- Move all component files to src/components/ directory for better organization
- Add comprehensive test suite with async/await patterns for proper render timing
- Fix critical TUI differential rendering bug when components grow in height
  - Issue: Old content wasn't properly cleared when component line count increased
  - Solution: Clear each old line individually before redrawing, ensure cursor at line start
- Add test verifying terminal content preservation and text editor growth behavior
- Update tsconfig.json to include test files in type checking
- Add benchmark test comparing single vs double buffer performance

The implementation successfully reduces flicker by only updating changed lines
rather than clearing entire sections. Both TUI implementations maintain the
same interface for backward compatibility.
