FN-7628: allow editing sent chat messages and rewinding agent responses
Adds the ability to edit a previously sent message in an agent chat, which rewinds the session/task room and regenerates the response from the edited message.
- Add chat-store support for locating/replacing a message and truncating subsequent history for a rewind
- Add a chat-manager rewind-session flow and a new register-chat-routes endpoint to rewind a room to an edited message
- Add legacy API route wiring and useChat hook support for issuing an edit request
- Add ChatView/StandardChatSurface/TaskPlannerChatTab UI affordances (edit control, styling) to trigger message edits
- Add a changeset documenting the new chat message-edit capability
- Add unit/integration tests covering chat-store rewind logic, chat-manager rewind-session behavior, chat routes, useChat, and ChatView edit UI
