feat(view) add local directory origin adapter for views & cache operations#23
Conversation
Add origin adapter abstraction to support querying packuments from different sources: - CacheAdapter: Wraps existing cache-based packument storage - LocalDirAdapter: Reads JSON files from local directory - createOriginAdapter: Factory auto-detects origin type Views can now be defined over local directories using: - Relative paths: ./local-data/ - Absolute paths: /data/npm-archive/ - file:// URLs: file:///path/to/dir/ This enables comparing npm cache against local snapshots, archived data, or exported packument sets.

LocalDirAdapter in src/view was reimplementing the storage driver
interface with different method names (keys/fetch vs list/get).
Moving it to src/cache as LocalDirStorageDriver:
- Implements proper storage driver interface (list, get, has)
- Read-only stubs for put, delete, clear
- createStorageDriver({ LOCAL_DIR: path }) creates the driver
- isLocalPath() exported for origin detection
- View query.js simplified to use cache directly
- CLI detects local paths and creates appropriate driver
This enables mounting local packument directories as virtual caches
for any cache consumer, not just views.
