Release 0.2.2 — browse submitted changelists, People & Roles, AI summaries

- History: GitHub-style split view of submitted changelists; preview file
  contents at their exact revision (code/image/3D/uasset) via `p4 print`
- People & Roles modal: who works on the depot, activity indicators,
  group/role assignment (p4 users / groups / group -i)
- AI commit summaries via OpenRouter (sparkle button); key/model in Settings
- Commit-message draft persists until Submit (not cleared on local commit)
- Resizable History file-list column (pointer-capture drag)
- Fix UI-scale leaving a gap at the bottom (compensate zoom in .win height)
- Author avatars on history rows; bump version to 0.2.2
