feat: update pack handling and character image paths; implement installed packs revision tracking

- Updated character images for Tekken 8, including Jin, Jun, Kazuya, and others.
- Introduced a new pack configuration system to manage character packs from a Gitea instance.
- Added types for pack management, including PackCharacter, PackManifest, and PackRegistry.
- Implemented functions to register and unregister installed packs, allowing dynamic character loading.
- Enhanced the character image retrieval system to support both bundled and installed packs.
