Also enables zeroize's `serde` feature so Zeroizing<String> can
round-trip through serde_json.

Reviewer note: flatten semantics of serde tag = "type" means no *Core
struct may ever use "type" as a field name.

Clean break from v1 — no migration. Decrypting a v1 blob now returns
IdfotoError::UnsupportedFormatVersion { found: 0x01, expected: 0x02 }.

derive_master_key now:
- length-prefixes passphrase and image_secret to eliminate concatenation
ambiguity (H1)
- normalizes passphrase to UTF-8 NFC before hashing
- returns Zeroizing<[u8; 32]> so the master key is wiped on drop (H2)
- wraps the intermediate password buffer in Zeroizing for the same reason

Code review fixups:
- ItemId/FieldId need impl Default delegating to ::new() to silence
clippy::new_without_default
- FieldId was missing the parallel uniqueness test that ItemId has

16-char hex (64-bit) random IDs for items and fields (audit M8).
AttachmentId is sha256(plaintext)[..16] for content-addressing.

Code review flagged that chrono's clock feature requires wasmbind for
WASM builds — without it Utc::now() will fail at runtime in the
idfoto-wasm crate. Also drops the redundant hex entry in
[dev-dependencies] (already in [dependencies]).

The getrandom crate (transitive dep via rand/argon2) requires the
"js" feature flag to compile for wasm32-unknown-unknown targets.

The ManifestEntry was being written with group: None instead of
preserving the entry's existing group value during edits.

Add optional group: Option<String> to both Entry and ManifestEntry for
logical organization (e.g. "work", "personal"). Backwards-compatible via
skip_serializing_if so existing vaults deserialize with group: None.
Includes three new tests verifying round-trip and legacy deserialization.

Corrected zig-zag scan positions from 4-15 to 6-17 (verified against
standard JPEG zig-zag ordering). Fixed inverted HVS luminance reasoning
to correctly explain that luminance is used because it isn't spatially
subsampled by JPEG, not because of visual sensitivity.

Document every public function, struct, field, constant, and non-trivial
private function across idfoto-core and idfoto-cli. Module-level docs
explain each module's role in the architecture. Comments explain the "why"
(crypto choices, algorithm design, data model rationale) not just the "what".

Adds dimension-search crop recovery that tries candidate original sizes
to reconstruct the embed grid, and fixes test imports for GenericImageView.

Implements DCT-based steganography module that hides 256-bit secrets in
JPEG luminance channel using Quantization Index Modulation (QIM) with
redundant copies and majority voting for reliable extraction.
