Push live updates to the UI while agent runs execute

Engine-side writes - hires, delegated tasks, chat messages, run state -
only reached the renderer after a run finished: the queue worker sent
one snapshot-changed at the end, and nothing fired at claim time, so
the window sat frozen for the minutes a CEO run takes unless the user
reloaded by hand. The execution service now takes a notifyDataChanged
callback, the agent loop fires it after every tool-bearing iteration,
and the worker announces the claim itself, so the UI follows the
company working in real time.
