Scan reads UDF and the AACS files before the drive handshake and records
a missing DVD /AACS key file instead of failing. Decryption needs an
explicit AACS unit base and refuses off-grid units; an all-broken
host-cert list is its own error (E7033). Every whole-disc and image to
ISO copy goes through one shared reader that refuses an unkeyable file
up front (E7032). HD DVD XPL tick and timecode fixes; CI action bumps.
