Matthew Jackson e308c5b825 aacs/types: redact Debug for all key-bearing types (test-guarded)
DeviceKey/HostCert/Vid/MediaKey/Vuk/ProcessingKey/UnitKey/DiscEntry carried key
material on #[derive(Debug)] — a stray {:?} would leak device/host-private/media/
volume/unit keys. Manual Debug impls print shape only. redaction_tests asserts no
key bytes appear and a redaction marker is present (fails if a derive returns).

Matthew Jackson edc60582ec FMTS: resolve the index key map from one forensic keyserver query
The keyserver protocol now returns all 32 index keys as an array for a
forensic content sample (and a single-element array for plain content).
resolve_fmts_key_map sends one forensic batch and maps array element i to
segment index i+1, replacing the per-index blind-probe collection loop
that repeatedly hit the key service. Segment/index parsing and the
aligned-unit content classification are reworked to support this:

- rename variant_select -> index_select (per-index, not per-variant)
- content classification moves to is_clean(buf, ContentFormat) so the
  unit selector emits only units the key service accepts
- segment.rs: parse IndividualSegment.tbl index tags + SPN ranges,
  build contiguous LBA key ranges from the resolved 32-key array
- decrypt/decorator plumbing for the resolved per-index keys

Fail loud (FmtsKeyMissing) when the forensic query returns < 32 keys or
any segment index stays unresolved.

Matthew Jackson 43cbfa07f5 1.3.2: AACS 2.1 FMTS variant-decode foundation
Add UnitKey.variant_number (0 = ordinary, 1..32 = forensic variant) with new/variant constructors, and aacs::variant_select — resolve a disc's single variant and classify each aligned unit (default / variant / drop foreign / conceal keyless). Correct IndividualSegment.tbl: the per-record field is the variant (cycles 1..32 on a retail disc), not a segment number — Segment.number -> Segment.variant.

Matthew Jackson 122a03b23d aacs: remove boil veneer; move key newtypes to aacs::types
leak-guard / leak-guard (push) Successful in 8s
aacs::boil was a thin newtype veneer over aacs::derive — a duplicate layer.
Delete it: move the shared key newtypes (Vid, MediaKey, Vuk, ProcessingKey,
UnitKey) into aacs::types, and expose resolve_candidate + KeyCandidate from
aacs::derive directly. Downstream (keysource, disc::encrypt) now import from
aacs::{derive,types}. Pure API consolidation, no behaviour change; full test
suite green on Rust 1.86.

Matthew Jackson decb87a250 AACS pipeline reshape + TrueHD metadata + central consts + clippy/fmt clean
- AACS: delete in-lib keydb parser (Step 3); boil-down primitives
  (mk_from_dk/vuk_from_mk/uk_from_vuk) + newtypes; KeySource->get_uk(ctx)+
  ResolveCtx; Unlocker->unlock()->Result<Vid,UnlockError> + AacsCertUnlocker;
  OEM bus-key gate (AacsBusKeyUnavailable); structured ResolutionTrace (Step 4).
- TrueHD: sample-rate from major-sync, Atmos label, 44.1k AU duration.
- consts: central media/format constants module; 17 duplicate const-defs
  centralized (sector/TS-packet/source-packet); mpls stream-entry + category
  codes named.
- clippy --all-targets -D warnings clean (1.86); fmt clean; 2199 lib tests.
