Summary

Fix socket singleton lifecycle: add and auto-reset on disconnect so page remounts always get a fresh authenticated connection
Add explicit WebSocket transport preference () to avoid polling fallback
Filter socket events by to prevent cross-conversation event bleed when switching conversations mid-stream
Use pattern so event handlers see current without stale closures or listener re-registration on every render
On , append accumulated streaming text as assistant message to local state (matching TUI approach; Pi session is in-memory so DB reload would miss the assistant response)
Preserve REST persist of user messages for conversation history on page reload
Clear streaming state on conversation switch
Fix : show animated typing indicator before first token arrives (previously returned when text was empty)
Fix : exclude worktree auto-generated docs from format check (pre-push hook blocker)

Test plan

Login to web UI and navigate to /chat
Create a new conversation via '+ New' or the Start button
Send a message — verify user message appears immediately, streaming indicator shows, assistant response streams in and is appended on completion
Switch between conversations — verify streaming state clears, messages load correctly for each conversation
Send message without selecting a conversation — verify auto-creation works
Verify no duplicate messages or stale events from previous conversations

Closes #120

- Fix socket singleton lifecycle: add destroySocket() and auto-reset on disconnect
  so page remounts always get a fresh authenticated connection
- Add explicit WebSocket transport preference to avoid polling fallback
- Filter socket events by conversationId to prevent cross-conversation bleed
  when switching between conversations mid-stream
- Use activeIdRef pattern so event handlers see current activeId without
  stale closures or listener re-registration on every render
- On agent:end, append accumulated text as assistant message to local state
  (matching TUI pattern; Pi session is in-memory so DB reload would miss it)
- Preserve REST persist of user messages for conversation history on reload
- Clear streaming state on conversation switch
- StreamingMessage: show animated typing indicator before first token arrives

chore: exclude .claude/ worktree docs from Prettier formatting check

ci/woodpecker/push/ci Pipeline was successful

Details

d468e248c2

The .claude/worktrees/ directory contains auto-generated markdown reports
from the QA automation system that are not authored code and should not
be subject to Prettier style enforcement.
