Matthew Jackson 4031513574 audit: module-by-module code audit fixes and test coverage
Lands the code-audit branches for aacs, css, keys, labels, udf, ifo and
dvd, bdnav/mpls/clpi, disc/bluray, extract, io, scsi, the mkv, mp4,
network and mpg muxers, the audio and video codecs, and CI. Fixes
include MKB and FMTS validation, UDF bounds, IFO fallback to the BUP,
DTS Express framing, MPEG-2 field pairing and mpg re-basing; the rest
pins existing behaviour with tests.

Matthew Jackson 9f43ae94d3 Comment and Documentation Cleanup
- Cap every inline `//` comment block at 3 lines; distil the rationale
  rather than delete it. Enforced by a new comment-guard CI check.
- Fix stale and orphaned rustdoc: broken intra-doc links (renamed or
  removed items), doc blocks that had merged onto the wrong item (leaving
  the intended item undocumented), and doc-contradicts-code drift.
- Add a doc-links CI check (cargo doc, deny broken intra-doc links) so
  both classes of comment rot are caught going forward.

Matthew Jackson 31a87ae994 Fix audit findings: DTS AMODE bound, key-fetch negative memoization, PGS probe coverage
- dts: accept all 16 legal AMODE channel-arrangement codes (0-15), not just
  0-9. Per ETSI TS 102 114 the 6-bit AMODE field has 16 defined arrangements;
  only 16-63 are reserved. a reference decoder the spec per-AMODE channel table confirms 10-15 are
  decodable 6/7/8-channel layouts. The old bound of 10 dropped spec-legal
  multichannel core frames as undecodable, silencing recoverable audio. Add a
  regression test (literal 0..16 range) that fails if the bound reverts to 10.

- keysource: only memoize a NEGATIVE (empty) key-fetch result when every source
  genuinely ran and none held the key — never when a source Err'd (network down,
  unreachable). A transient outage was being cached as a permanent "no key" for
  the fingerprint, permanently dropping a unit that could be recovered once the
  source came back. Thread an `errored` flag out of the drivers and gate the
  cache insert on it. Tests cover both the recover-after-outage case and that a
  genuine absence is still memoized.

- pgs_forced_probe: add happy-path coverage feeding real synthetic BD-TS PGS
  display sets through the full demux -> parse -> observe -> apply path, both a
  forced verdict landing and a non-forced verdict clearing a vendor flag.

- mp4: correct fit_report doc (audio carried is AC-3/E-AC-3 AND DTS/DTS-HD).

- scan_iso test: add independent fixture expectations (volume id) so the parity
  test is no longer purely tautological against a re-run of the same composition.

Matthew Jackson 925f4d56f6 Add scan_iso entry point for file-backed ISO scans
Introduce libfreemkv::scan_iso(path, opts) -> (Disc, Box<dyn SectorSource>),
the file-backed counterpart to DiscSession::scan. It is the single place
that opens a FileSectorSource, reads its capacity, and runs Disc::scan_image,
returning the scanned Disc plus a reusable reader over the same image so
consumers stop hand-rolling that triple.

Add an integration test that materialises a minimal synthetic UDF image to a
real file, asserts scan_iso matches the manual open+scan_image composition,
and confirms the returned reader is still usable (capacity + sector read).
Also covers open-failure and scan-failure error propagation.
