fix(coding-agent): fixed stale loader recovery and updated catalog model constraints

- Stopped and cleared the working loader before auto-compaction and auto-retry.
- Ensured stale loadingAnimation is removed so agent_start recreates the Working loader.
- Set catalog model input/output costs to 0.09/0.18 and reduced maxTokens to 65536.
