Route DVD PS demuxer through codec parsers, fix CSS test expectations
...
- DVD PS path now calls parser.parse() like BD-TS path does
- MPEG-2 sequence headers extracted for codec_private
- Keyframe detection from parser instead of always-true
- Fix CSS roundtrip tests: descramble uses TAB1 permutation, not pure XOR

Unified Stream trait: read() and write() on one type
...
Stream trait: read() returns PesFrame, write() accepts PesFrame.
A stream is a stream — you read from it or write to it.
No separate Input/Output traits.
API: libfreemkv::input(url) and libfreemkv::output(url, title, codecs)
Returns Box<dyn Stream>.

CSS + AACS cross-validation test vectors
...
AACS: encrypt with aes crate independently, decrypt with our code, verify match
- 3 tests: unit decrypt, alternate key, bus decrypt
- Uses independent AACS IV constant (not imported from library)
CSS: roundtrip snapshots + Stevenson attack validation
- 4 tests: snapshot regression, multi-key roundtrip, attack validation
- Documents limitation: synthetic sectors may not converge on attack
320+ tests total.
