fix(coding-agent): bind extension UI context on startup

packages/coding-agent/CHANGELOG.md

@@ -6,6 +6,7 @@
 
 - Git extension updates now handle force-pushed remotes gracefully instead of failing ([#961](https://github.com/badlogic/pi-mono/pull/961) by [@aliou](https://github.com/aliou))
 - Extension `ctx.newSession({ setup })` now properly syncs agent state and renders messages after setup callback runs ([#968](https://github.com/badlogic/pi-mono/issues/968))
+- Fixed extension UI bindings not initializing when starting with no extensions, which broke UI methods after `/reload`
