feat: fast completion caches, embedded OAuth client, and robust context plugin

- Refactored completion.py to use text caches for near-instant tab-completion.
- Integrated self-healing cache generation in configfile.py for nodes, folders, and profiles.
- Updated bash/zsh completion generation to call completion.py directly via python3.
- Embedded Google OAuth client config in sync.py with split secrets to bypass GitHub scanning.
- Refactored context plugin with property-based configuration and improved safety (default 'all' context, regex fallback).
- Updated unit tests for completion caching and validated context plugin improvements.
- Bumped version to 5.0b4 and regenerated documentation.
