Farcaster cast search

Search Farcaster casts by keyword (literal, semantic or hybrid match), newest first, optionally filtered to one author or channel. Returns compact casts: hash, author (fid, username, follower count), text, timestamp, channel, reactions, reply count, embed URLs. Use for mention monitoring, sentiment sampling, or finding discussion of a token, product or topic.
