## Why
Client permission definitions and constraints can differ from those on the connected app server. Accepted permission changes also need to survive task transitions before their settings notifications arrive.
## What changed
- Discover permission profiles and availability from the connected server and apply selections through `thread/settings/update`, including custom profiles.
- Adopt the server's effective permission settings instead of reapplying local definitions or constraints.
- Retain accepted selections and effective approval settings across new tasks, forks, side conversations, directory changes, reconnects, and safety retries without blocking navigation on a settings notification.
- Recognize the current built-in permission preset when the server supplies an unnamed profile.
## Testing
Add regression coverage for conflicting client/server profile definitions, rejected and unchanged selections, consecutive requests with omitted approval settings, and permission carryover before confirmation. Extend discovery and menu tests to verify server-provided availability and unnamed-profile highlighting.
