open() works on all drives, AACS 2.0 handshake wired, raw_gc_010c on DriveId

- DriveSession::open() no longer requires profile match — works on any optical drive
- init()/probe_disc() return error gracefully for unknown drives
- find_drives() returns all optical drives (PDT 0x05), not just profile-matched
- has_profile() check for callers
- AACS 2.0: handshake wired into resolve_aacs() — real VID + read_data_key
- DriveId: added raw_gc_010c field for GET_CONFIG 010C response bytes
