chore(card-data): refresh MTGJSON token & subtype catalogs

[matthewevans]

Automated refresh of the engine-embedded card-data catalogs from the latest MTGJSON publish.

• crates/engine/data/known-tokens.toml — named-token catalog (tokens-gen)
• crates/engine/data/oracle-subtypes.json — creature-subtype vocabulary (oracle-gen --write-subtypes)
• crates/engine/data/mtgjson-vintage — vintage write-gate stamp

Generated by PHASE_REFRESH_MTGJSON=1 scripts/gen-card-data.sh; the vintage gate only promotes catalogs when the MTGJSON input date advances, so this diff reflects a genuine upstream data change. Review, then let it auto-merge once CI is green.

Summary by CodeRabbit

• New Features

  • Added structured data for the Elf Warrior token, including stats, colors, sources, references, and image information.
  • Expanded token source-card associations, including Tolabow, Loch Rascal and Seize the Spoils.
