DVD vob_start absolute rebase + rc.5.3 audit fixes
- ifo.rs: rebase VTS title VOBS to absolute disc LBA (file_start_lba +
vtstt_vobs); fixes DVD rips opening on the menu region instead of the
movie (e.g. SOTL). Adds absolute-placement regression test.
- aacs/boil.rs: add mk_from_pk primitive (PK -> MK via MKB walk).
- dvdnav/: nav-VM command decoder + start-cell resolver seam, parked
behind USE_NAV_RESOLVER (kept compiled, never executed).
- mux: FVI src.byte within-sector per spec; Unknown colour -> CICP
unspecified (2,2,2,1); demux clear PCS -> NORMAL; ts.rs feed() base
reset + boundary provenance fix.
- Assorted audit fixes (doc/comment/test accuracy) across the crate.
