Thanks so much for this, Jonathan — really strong work: the OAuth (PKCE) connectors, browse/select, and the ingestion pipeline are exactly what we needed.

After thinking about where it best fits, we've relocated the collector framework to FreeEedCloud, which is the natural home for cloud data collection (it lives alongside the serverless collection/processing pipeline there). It's imported with your authorship preserved as Scaia-ai/FreeEedCloud#14.

Closing this PR in favor of that one. Much appreciated — thank you!
