Typesense v30.2

This release fixes some important bugs identified in v30.1.

Bug Fixes

• [v30.2] Fixed incorrect handling of numeric != filters in both lazy and eager filter execution, including explicit not-equals lists on range-indexed numeric fields.
• [v30.2] Fixed highlighting to correctly mark single-token phrase matches and to avoid race conditions during union searches that run alongside concurrent writes.
• [v30.2] Fixed missing synonyms, stem, and stemming_dictionary fields in curation GET responses.
• [v30.2] Fixed a number of edge cases in diversity search.
• [v30.2] Fixed union search deduplication so curated pinned hits are no longer collapsed.
• [v30.2] Fixed a bug related to reference faceting.
• [v30.2] Fixed vector search behavior so zero-match phrase queries still preserve vector search results.
• [v30.2] Fixed scoped API key handling so embedded collection parameters can supply a missing collection in multi-search requests.
• [v30.2] Fixed conversation search error handling so failed searches do not incorrectly reuse the first search collection.
• [v30.2] Fixed search cache keying so scoped API key parameters and request-specific embedded params do not collide in the cache.
• [v30.2] Fixed JSON response escaping by using nlohmann::json::dump() when serializing response payloads.
• [v30.2] Fixed /health responsiveness during heavy bulk inserts by routing health checks to the meta thread pool.
• [v30.2] Fixed HTTP/2 async import teardown on early exit.
