- AttachmentId now uses 16 bytes of SHA-256 (128 bits) instead of 8,
requiring ~2^64 work for birthday collision instead of ~2^32.
- Added is_valid() to ItemId and AttachmentId for path traversal
prevention during backup restore.

Renames crate directories and sweeps identifiers so Plan 1B can reference
the post-rename names throughout.
- git mv crates/idfoto-{core,cli,wasm} → crates/relicario-{core,cli,wasm}
- sed sweep: idfoto_core/idfoto-core/IdfotoError/IDFOTO_IMAGE/.idfoto/ etc.
- All 128 relicario-core tests pass post-sweep
