Owner

Summary

Phase 7 — Message Editing: Users can edit their own messages after sending.
Admins and moderators can edit any message. An (edited) label appears on modified
messages, and edits propagate in real time over WebSocket.
Phase 8 — Typing Indicators: Shows "Alice is typing…" above the composer when
another user is actively composing a message in the same room or DM. Purely
ephemeral — no database writes.

Changes

Phase 7 — Message Editing

DB migration: adds edited_at TEXT column to messages
New edit_message server function — validates ownership (or mod/admin role),
enforces max_message_length, writes to DB, broadcasts ChatEvent::MessageEdited
over WebSocket
Message model gains edited_at: Option
Room view and DM view: inline edit UI on hover (textarea + Save/Cancel),
(edited) label, WS event handler to refresh on remote edits
Integration tests: owner can edit, non-owner is rejected, soft-deleted message
is rejected, empty/oversized body is rejected

Phase 8 — Typing Indicators

New ChatEvent::UserTyping and ChatEvent::UserStoppedTyping server→client events
New ClientControl::Typing client→server frame
Hub: stores (room_id, user_id) → Instant typing state; broadcasts UserTyping on
the first keystroke of a new session; spawns a 5s eviction task that sends
UserStoppedTyping on silence; excludes the sender from their own broadcast
WsHandle gains send_typing(room_id)
Room view and DM view: debounced typing frame (at most once/sec on oninput),
Signal<Vec<(user_id, username)>> for currently-typing users, "Alice is typing…"
label above the composer

Test plan

Build passes: just dev-web
Edit a message you sent — inline editor appears, save updates in place with
(edited) label
Attempt to edit another user's message — edit button should not appear
Open two sessions in different browsers, join the same room — typing in one
shows indicator in the other; stops after 5s of silence
Test typing indicator in a DM conversation
Run integration tests: just test
