Closed #146

This PR fixes AI element dependency generation in the registry builder.

1. Standardizes AI element imports to always use relative paths, allowing the registry service to correctly infer cross-component dependencies.
2. Updates the registry builder to emit full, URL-based registryDependencies for AI elements while skipping self and group-internal files.
3. Additionally, this PR adds all.json support for bulk component installation:

• Generates all.json as a RegistryItem containing all components for bulk installation
• Improves dependency analysis with @types/ mapping and normalized package name resolution
• Migrates from index.json to registry.json for consistency
