Bump version to 0.2.2

Changes since 0.2.1:
- Keyboard shortcuts: Ctrl+K palette + Ctrl+Shift+E/O/W for
  split-right / split-down / close, Ctrl+Shift+B per-pane and
  Ctrl+Shift+Alt+B global broadcast, Ctrl+Shift+Arrow for spatial
  pane navigation
- New panes default to WSL home (~) instead of inherited Windows cwd
- Resize artifacts: rAF-throttle gutter drag, debounce PTY resize,
  skip resizePane when cols/rows haven't actually changed (kills the
  idle-flap loop that surfaced with many panes)
- Minimum pane size (180px) enforced on both split and gutter drag
- 2px gap around each leaf so per-pane borders read as distinct
  rectangles instead of a continuous grid
