Rewrite CSS from Stevenson 1999 paper — proper table-driven cipher
- tables.rs: 5 CSS specification tables (TAB1-TAB5, mathematical constants)
- lfsr.rs: Table-driven LFSR1 (TAB2/TAB3) + LFSR0 (TAB4), sector seed XOR,
decrypt_key() mangling function, descramble_sector() with proper feedback
- crack.rs: Stevenson divide-and-conquer attack (2^16 LFSR1 iteration,
LFSR0 deduction from known plaintext, 10-byte validation)
- No external code copied — original Rust implementation from the 1999 paper
- 225 tests, 0 ignored
