Original GitHub issue: https://github.com/morluto/rea/issues/324

Implement the native Node-API adapter that opens each authority-relevant path component with CreateFileW (FILE_FLAG_OPEN_REPARSE_POINT, FILE_FLAG_BACKUP_SEMANTICS), inspects attributes and reparse tags, and records stable volume/file identity.

Acceptance:

Rejects disallowed symlinks, junctions, mount points, and unknown reparse tags.
Supports NTFS and explicitly fails closed on unsupported filesystems.
Volume identity is canonical 16-hex; file identity is canonical lowercase hex of FILE_ID_INFO.
Requested-path mismatches and malformed observations return native_contract_mismatch.

Part of #289.
