chore: reconcile Plan 1A branch with idfoto→relicario rename

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
