Keep quick chat warm and restore the last opened conversation per project.
- persist the active quick chat session id in per-project local storage and restore it before falling back to latest activity
- retain in-memory quick chat state across close/reopen while resetting chat state correctly when the project changes
- add storage, hook, and FAB coverage for restored sessions, warm reopen behavior, and project switching; document the updated quick chat behavior

Ensure the first Quick Chat message reliably streams even when a stale sendMessage closure sees no active session.
- trigger a microtask flush for queued pre-session sends when a session is already active and no stream is running
- preserve existing streaming guards so flush only runs when safe
- add regression coverage for stale-closure first-send flow to verify stream start and completion behavior

Ensure a user's first quick-chat message is preserved and sent once session initialization finishes.
- queue pre-session text sends as promise-backed pending work instead of returning early
- flush queued text after session activation and wire completion/rejection to the original send promise
- clear queued completion state on stream reset paths and add regression coverage for first-send-before-init flow

- Remove fetchAllMessagesInChat/fetchAllMessages helpers
- Keep limit:50 for initial load in useChat and useQuickChat
- Add IntersectionObserver sentinel at top of ChatView message list to
trigger loadMoreMessages() when user scrolls to the top
- Keep stale-session guards (activeSessionRef checks) from original PR
- Tests: revert assertions back to { limit: 50 }
Both useChat (full ChatView) and useQuickChat (FAB) loaded only the first 50
messages on open and never paginated further. In useChat, loadMoreMessages
exists but ChatView never calls it — dead code. In useQuickChat, there was
no pagination at all.
Fix: add fetchAllMessagesInChat / fetchAllMessages helpers (paginate through
the API 200-msg cap), replace all limit:50 initial-load call sites, and
add stale-session guards via activeSessionRef before calling setMessages.
hasMoreMessages is set to false after a full initial load.
Forward-pagination path in useChat (isPaginationRequest=true) is preserved
for backward compat.
Fixes chat hooks to flush queued messages when recovery completes, preventing stale messages from lingering in useChat and useQuickChat; includes tests for both hooks.

Three interacting bugs caused "Failed to initialize chat" toast spam and
prevented fresh session creation:
1. Race condition in handleCreateFreshSession — setting chatMode/
selectedAgentId before startFreshSession triggered the session-init
useEffect, which called switchSession and resumed the old session
instead of creating a new one. Fixed with skipNextSessionInitRef.
2. Infinite retry loop — shouldRetrySessionInit retried indefinitely
when initializeSession failed, producing unbounded toast spam.
Fixed with a 3-retry cap (initRetryCountRef).
3. Cascading re-renders — switchSession depended on activeSession in
its closure, getting a new identity on every state change and
re-triggering the consumer's useEffect. Fixed by reading
activeSession from a ref instead.

Backend
- chat.ts now routes both regular chat and QuickChat through
createResolvedAgentSession instead of branching to createFnAgent for
the no-runtime-hint case. This removes the divergent path where
pi-ai's cleanupSessionResources(sessionId) could tear down resources
the next generation depends on.
- sendMessage's finally only disposes the agent if it still owns the
activeGenerations slot. A newer generation that has pre-empted us
cleans up its own agent in its own finally — disposing here would
yank the underlying CLI process out from under it.
- __setCreateFnAgent test helper now mirrors its mock into the
createResolvedAgentSession slot so existing test setups still work
after the unification.
Frontend
- Extract createChatStreamHandlers (RAF coalescing, accumulators,
tool-call dedup, fallback handling) — useChat and useQuickChat were
duplicating ~85 LOC each. Both now compose the shared factory.
- Move shared chat types into chatTypes.ts. The hooks re-export them
for backward compatibility with existing consumers.
- Removed per-message Markdown/plain-text eye toggles. A single
thread-level toggle in the chat header now flips every assistant
bubble (including the streaming one) between rendered Markdown and
plain text.
- Model-only chats hide the per-message agent identity row entirely;
the model name is already in the thread header.
Tests
- Updated ChatView tests to reflect the new render-toggle contract
(single header toggle drives all bubbles) and the model-only avatar
suppression.
