Adds zstd, tar, base64 to relicario-core; introduces
BackupBadMagic / BackupUnsupportedVersion / BackupSchemaMismatch.
Foundation for the backup module landing in Task 2.
Also ports TOTP RFC 6238 compute to relicario-core::item_types::totp
so native + CLI + WASM share one implementation (audit H5: CSPRNG
via core's Uniform-sampling generator).
Adds hmac = "0.12" and sha1 = "0.10" to relicario-core deps to support
HOTP/TOTP HMAC with Sha1/Sha256/Sha512. RFC 6238 test vector (t=59,
SHA-1, 8 digits) passes: "94287082".
Resolves conflicts from merging origin/main (idfoto→relicario rename):
- Kept Plan 1A's typed-item vault.rs, lib.rs, integration.rs over main's
old entry-based versions
- Took main's relicario_dir() fix in CLI main.rs (sed had missed idfoto_dir)
- Kept Plan 1A's UnsupportedFormatVersion error variant in crypto.rs
- Kept Plan 1A's opaque Decrypt message (audit M4) in error.rs
- Deleted entry.rs (replaced by item.rs + typed modules in Plan 1A)
- Resolved Cargo.toml description to main's "relicario password manager"

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
