• fix: Remove unused imports and add biome-ignore for false positive

  - Remove unused SlashCommand import from tui-renderer.ts
  - Add biome-ignore comment for previousRenderCommands which is actually used

• 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

• 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

• 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

• fix(tui): Trigger initial render when start() is called

  The demos were not showing any output until user input because:
  - Components were added before ui.start() was called
  - addChild calls requestRender() but it returns early if \!isStarted
  - So no initial render happened until user input triggered one
  
  Now ui.start() triggers an initial render if components exist.

• tui: Implement surgical differential rendering for minimal redraws

  - New renderDifferentialSurgical method with three strategies:
    - SURGICAL: Only update specific changed lines (1-2 lines per render)
    - PARTIAL: Clear and re-render from first change when line counts change
    - FULL: Clear scrollback and re-render all when changes above viewport
  - Preserves all content in scrollback buffer correctly
  - Reduces redraws from ~14 lines to ~1.3 lines for common updates
  - All 24 tests pass including scrollback preservation tests
  - Massive performance improvement: 90% reduction in unnecessary redraws

• tui: Fix differential rendering to preserve scrollback buffer

  - renderDifferential now correctly handles content that exceeds viewport
  - When changes are above viewport, do full re-render with scrollback clear
  - When changes are in viewport, do partial re-render from change point
  - All tests pass, correctly preserves 100 items in scrollback
  - Issue: Still re-renders too much (entire tail from first change)

• 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.

• Initial monorepo setup with npm workspaces and dual TypeScript configuration

  - Set up npm workspaces for three packages: pi-tui, pi-agent, and pi (pods)
  - Implemented dual TypeScript configuration:
    - Root tsconfig.json with path mappings for development and type checking
    - Package-specific tsconfig.build.json for clean production builds
  - Configured lockstep versioning with sync script for inter-package dependencies
  - Added comprehensive documentation for development and publishing workflows
  - All packages at version 0.5.0 ready for npm publishing
