Matthew Jackson 6e14fc0c0c libfreemkv: 1.7.0 groundwork — sector-recycle soundness + CI hardening

Security
- Remove the unsafe Vec::set_len over recycled sector buffers — UB reachable
  from safe code (GHSA-j8ww-f5fg-9pmh, low). Uses Vec::resize; pooling unchanged.

CI / tooling
- clippy on stable with the MSRV single-sourced from Cargo.toml; cargo-deny
  dependency-audit gate with first-party git sources allowed (#15); audience-based
  comment-guard (#17).

Docs
- README (keydb ownership, BD-J parser count), drive-access transport/reset
  notes, mux timeline module-doc links.

Raw Blame History

`BitReader` (mux/codec/startcode.rs)

Minimal MSB-first bit reader over an RBSP, for the leading fields of a coded slice header (H.264 first_mb_in_slice + slice_type; HEVC slice_segment_header).

It does NOT remove emulation-prevention bytes (00 00 03). Those can only appear after two consecutive 0x00 bytes, which cannot occur within the first Exp-Golomb codes of a slice header (a slice header never begins 00 00), so the leading fields this reader is used for decode correctly. A caller reading deep enough into a header that 00 00 03 could appear must de-emulate the RBSP first.
