- Delete unused bloom.ts module (leftover from topic-based discovery) - Remove maxTopicsPerOffer configuration (no longer used) - Remove unused info field from Offer types - Simplify generateOfferHash() to only hash SDP (remove topics param) - Update outdated comments referencing deprecated features - Remove backward compatibility topics field from answer responses This completes the migration to V2 service-based architecture by removing all remnants of the V1 topic-based system. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
