feat(web+nomos): fix chat streaming reactivity, unified activity timeline, tool cards in chat
- fix(web): Svelte 5 identity-based reactivity broke text_delta streaming —
immutable message objects in all three chat handlers so text streams live
- feat(web): streaming cursor + inline status indicator merged into message flow
- feat(web): expandable inline tool call cards in chat thread
- feat(web): merge Plan + Event log into one backbone Activity timeline —
filled status nodes, branch stubs, auto-scroll follow mode, per-session
activityLog, compact for the rail
- fix(nomos): add X-Accel-Buffering:no to /chat SSE (proxy buffering)
- fix(nomos): plan step auto-close SQL param bug (store.go)
- polish: timestamps, role labels, code copy button, table overflow, min
window size, delete AgentIndicator/ActivityTimeline dead code
