Module pruning 

Auto-pruning + dedup for the knowledge vector store (#688).

Strategies:

• Stale pruning: remove entries older than a threshold by source_type
• Content dedup: merge entries with near-identical content (prefix match)
• Source dedup: if same source_type+source_id has multiple entries, keep newest
