Implement Jade CLI v1.0 MVP

Complete implementation of note management CLI with all core features:

Commands:
- add: Create new notes in $EDITOR with auto-generated filenames
- list: Display all notes with titles, paths, and tags
- search: Full-text search via ripgrep, tag-based filtering
- tags: List all tags with occurrence counts
- edit: Fuzzy search and edit notes by title
- rm: Move notes to trash with confirmation prompt

Features:
- Automatic depository structure initialization (.jade/trash/)
- Configurable tag prefix (default '+')
- Parse title from first # heading (filename fallback)
- Extract tags anywhere in content
- Parse both [[wiki-links]] and [markdown](links)
- Trash system with timestamps to prevent conflicts

Technical:
- Global config at ~/.config/jade/config.yml
- Per-depository settings support
- Ripgrep integration for fast search
- $EDITOR integration for note editing
- Comprehensive README with usage examples
