- Add sender_type field to TypingEvent (user/ai)
- Change Redis TTL from 10s to 60s for AI typing persistence
- Broadcast typing.start/stop with sender_type=ai when AI stream starts/ends
- Replay active AI typing events from Redis on new WS subscribe
- Fix ai.stream_chunk WS payload missing display_name and chunk_type
- Add initial thinking chunk on AI stream start for immediate indicator
RoomMessageEvent was losing the AI model name because the
From<RoomMessageEnvelope> impl hardcoded display_name: None.
Add display_name to RoomMessageEnvelope and propagate it through
all AI streaming code paths (chat, ReAct, non-streaming).
Member messages keep display_name: None.
Add TypingEvent struct in queue::types for broadcast-based typing
indicators, and TypingStart/TypingStop variants in RoomEventType for
WebSocket event dispatch.
- Fix ReactionGroup.count: i64 -> i32 and users: Vec<Uuid> -> Vec<String>
to match frontend ReactionItem (count: number, users: string[]).
Mismatched types caused the WS reaction update to silently fail.
Also update ReactionItem in api/ws_types.rs to match.
- Add activeRoomIdRef guard in onRoomReactionUpdated to prevent stale
room state from processing outdated events after room switch.
- Switch from prev.map() to targeted findIndex+spread in onRoomReactionUpdated
to avoid unnecessary array recreation.
