feat(kanban): card detail modal and rich agent-run console

- RunEventList: grouped activity timeline. Assistant text becomes chat
  bubbles (auto-collapsing long messages); tool_start/tool_end pair into
  entries with spinners and expandable input/result blocks; bevy output
  rolls into a live console; relative timestamps on a left rail
- AgentRunBar: redesigned as a mission console. Live stats header (elapsed
  time, tool count, events), animated status banner with sweep/glow while
  running, clearer action bar. All controls preserved (run/steer/stop,
  diff/merge/bevy) so the human-only merge/complete safety model holds
- tailwind.css: vn-flow, vn-sweep, vn-dots, vn-spin keyframes
- CardModal: full card overlay (orchestrator, references, tags, comments)
- DiffModal: branch-diff review (commits, stat, capped patch)
- useOrchestrator: background polling + bevy status sync + ref-counted SSE
- KanbanCard: pulsing agent/bevy running badge on collapsed cards
