- Finding 1: add AppState::authed_get/authed_post helpers that attach
Bearer token when present; all 4 commands now use them
- Finding 2: MessageInput accepts onSent callback, calls it after
successful send; ChatPage passes refreshKey bump as onSent
- Finding 3: MessageList useEffect uses cancellation flag so stale
in-flight responses cannot overwrite a newly selected conversation
- Finding 4: scrollIntoView moved to separate effect keyed on
messages.length so scroll only fires when new messages arrive
Implement list_workspaces and list_conversations commands to enable
frontend access to workspace and conversation data via Tauri IPC.
- Add workspace.rs with list_workspaces command (GET /workspaces)
- Add conversation.rs with list_conversations command (GET /conversations?workspace_id=)
- Register both commands in lib.rs invoke_handler
- Update commands/mod.rs to expose new modules
