Eric Traut 01df50cf42 Add thread/shellCommand to app server API surface (#14988) ... This PR adds a new `thread/shellCommand` app server API so clients can implement `!` shell commands. These commands are executed within the sandbox, and the command text and output are visible to the model. The internal implementation mirrors the current TUI `!` behavior. - persist shell command execution as `CommandExecution` thread items, including source and formatted output metadata - bridge live and replayed app-server command execution events back into the existing `tui_app_server` exec rendering path This PR also wires `tui_app_server` to submit `!` commands through the new API.		2026-03-18 23:42:40 -06:00
