Restructure labels: detect-then-parse, named parsers, raw disc data

Architecture:
- Each BD-J format in own file: paramount.rs, criterion.rs, pixelogic.rs, ctrm.rs
- Standard interface: detect() → bool, parse() → Option<Vec<StreamLabel>>
- PARSERS array in mod.rs — drop in a new parser with one line
- Shared vocab.rs for BD spec codec names only (MLP→TrueHD, AC3→Dolby Digital)
- All other label data passes through raw from disc — no guessing

Changes:
- New: paramount.rs (playlists.xml — Paramount/onQ format)
- Renamed: bluray_project.rs → pixelogic.rs
- Renamed: stream_properties.rs → criterion.rs
- Merged: language_streams.rs + menu_base.rs → ctrm.rs
- Removed: jar module (superseded by labels), dead apply functions
- Added: DriveSession::eject() with PREVENT ALLOW MEDIUM REMOVAL
- Added: DiscRegion enum (Free/BluRay/Dvd)
- Fixed: capture sector ranges now include all files (only skip STREAM/)
- Renamed: StreamLabel.region → variant (not a BD spec field)
