Any time an agent creates a new node (WRITE_NODE) or the fact miner
stores extracted facts, a naming sub-agent now checks for conflicts
and ensures the key is meaningful:
- find_conflicts() searches existing nodes via component matching
- Haiku LLM decides: CREATE (good name), RENAME (better name),
or MERGE_INTO (fold into existing node)
- WriteNode actions may be converted to Refine on MERGE_INTO
Also updates the rename agent to handle _facts-<UUID> nodes —
these are no longer skipped, and the prompt explains how to name
them based on their domain/claim content.
- New agents/transcript.rs: shared JSONL parsing for enrich, fact_mine,
and knowledge (was 3 separate implementations, ~150 lines duplicated)
- New best_match() and section_children() helpers in neuro/rewrite.rs
(was duplicated find-best-by-similarity loop + section collection)
- Net -153 lines
