feat(agent): deprecate and completely remove cline agent support

- Delete adapters/cline.py and unregister from registry.py
- Remove cline branches from lib.sh and all 8 skill scripts (create, resume, stop, status, reconcile, update_yaml_resumed, resolve_session_id, orc_onboard)
- Narrow own-key mapping dictionaries across lib_py core modules to 4 supported agents
- Delete cline-exclusive tests and retarget shared fixtures to grok/hermes/claude
- Update skills documentation and installation guides (439 passed, 0 failures)
- Archive cline deprecation consensus and review reports
