Summary

AI summary

Automatically recovers from corrupted ChromaDB on startup, eliminating segfault loops.

Full changelog

Fix: Auto-Recovery on Startup

If ChromaDB gets corrupted (crash during indexing, power loss, etc.), the server now automatically detects and recovers instead of crashing with a segfault loop.

What was happening

A crash during indexing left the SQLite DB in a corrupted state
Next startup: segfault → crash → restart → segfault (infinite loop)
Required manual deletion of data/chroma_db/ to fix

What happens now

Server detects corruption on startup
Automatically deletes corrupted data
Recreates fresh collection
Logs [RECOVERY] messages so you know it happened
Zero manual intervention needed

Also handles

Embedding function conflicts (e.g., switching models)
Orphaned UUID directories from partial rebuilds
