v0.6.7 - Cited Research Filter & Maintenance

[0.6.7] - 2026-05-10

Added

• Cited-Only Filtering for Research — Added support for filtering out non-cited sources during research imports. This includes a robust citation parser that handles standard markers ([1]), ranges ([4-6]), and bibliography extraction. The research_status polling output now also annotates sources with a cited: bool field for visibility. Thanks to @zxyasfas for the contribution (PR #188)!

Fixed

• Audio Download Extension Validation (Issue #185) — nlm download audio now rejects incompatible file extensions (like .mp3 or .wav) instead of writing AAC data with the wrong file extension. A helpful hint now suggests using .m4a or .mp4 and provides an ffmpeg command for conversion.
• Conversation Query Hangs — Replaced direct client.post() with a fresh httpx.Client() context in conversation queries to prevent internal connection pool exhaustion or unexpected hangs during repeated querying.
• Fuzzy Title Matching in Research — Upgraded the research citation title matcher from basic substring checks to whitespace-aware boundary regex, preventing false positives where a short title matches a substring of a longer word.
