feat: migrate config to YAML, add dual-caching and 0ms fzf wrapper

- Migrated configuration backend from JSON to YAML for better readability.
- Added automatic dual-caching (.config.cache.json) to preserve fast load times with YAML.
- Implemented a new 0ms latency fzf wrapper for bash and zsh (--fzf-wrapper).
- Updated sync plugin to support the new YAML config format and clear caches on extraction.
- Refactored 'completion.py' to gracefully handle fallback config formats.
- Added new test modules (test_capture, test_context, test_sync) covering core plugins.
- Updated existing unit tests to handle YAML config creation and parsing.
- Bumped version to 5.0b3 and regenerated HTML documentation.
