Add multi-depository support with global config

- Implement global CLI config at ~/.config/jade/config.yml
- Add jade depo commands (add, list, remove, set-default)
- Support depository short names and context-aware detection
- Remove tag_prefix config, hardcode + syntax for consistency
- Update depository resolution: flag -> context -> default
- Auto-initialize .jade/ directory structure when adding depos
- Update documentation with new multi-depository workflow
