test(porting): differential tests against MoviePilot Rust-accelerated parsers

Snapshot differential tests (known deviations registered, current state passes):
- title/path recognition: 216 samples vs MP MetaInfo/MetaInfoPath
- filter rules: 42 rules x 28 torrents vs MP FilterModule
- RSS/indexer parsing: 15 feeds, 72 indexer samples
- zhconv: 69 samples
Generator: scripts/mp-sync/gen-differential.py; report: docs/porting/mp-rust-logic-parity.md
