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.

disc_tests: capacity/layer derivation
scan_image_reports_capacity_in_bytes_and_the_layer_count covers the scan
reporting the medium's size on both axes it exposes, derived from the one
sector count the caller hands in:
capacity_bytesis that sector count times the 2048-byte logical sector (ECMA-167 / BD-ROM logical block size). It is what sizes a full-disc image read and what the progress percentage divides by, so a wrong scale is a wrong ISO length, not a cosmetic number.layersdistinguishes single- from dual-layer media. The threshold sits between the two real capacities: a single-layer BD-25 is 12,219,392 sectors (25,025,314,816 bytes / 2048) and a dual-layer BD-50 is 24,438,784 sectors, so BD-25 must report 1 layer and BD-50 must report 2.
scan_image takes the sector count as a parameter, so this exercises the
real derivation without a 50 GB fixture.
