feat: add chess population module with VSA move encoding

- chess/populate.rs: VSA-encode positions, moves, and move sequences
  - encode_position() via ChessFingerprint (16K-bit)
  - encode_move() via Fingerprint::from_content("chess_move:{uci}")
  - encode_move_sequence() via permute+bundle (order-preserving)
  - encode_anchored_sequence() via bind(sequence, position)
  - find_similar_openings/lines() for similarity search
- 12 seed openings with UCI move data matching neo4j-rs aiwar module
- Purely additive: new file + re-exports in chess/mod.rs
