fix: bump retrieval_count in list_facts()

[angrywudu]

Bug

HolographicStore.list_facts() did not increment retrieval_count on returned facts. All other retrieval methods (search, probe, related, reason, contradict) correctly call _bump_retrieval_count(), but list — which is the primary way agents browse the fact store — was silently skipping it.

This meant facts frequently accessed via list never had their usage tracked, so the trust score system's frequency data was incomplete.

Fix

Added the same UPDATE facts SET retrieval_count = retrieval_count + 1 pattern used in search_facts() to list_facts(), applied after the SELECT and before returning results.

Testing

• Verified fix produces incrementing retrieval_count values across consecutive list calls
• Confirmed SQL UPDATE fires correctly against live database
• Gateway restart required to load patched module (old process had cached bytecode)
• All existing search/probe/related/reason/contradict bump behavior unchanged

Duplicate of #24527 and overlaps with omnibus #23221 — all fix retrieval_count not being incremented in holographic memory retrieval paths. See also #17899 (tracking issue).

Thanks for fixing the verified list_facts() omission. Current main returns selected list rows directly at plugins/memory/holographic/store.py:399-400, and the proposed batched update correctly mirrors the existing search_facts() update at plugins/memory/holographic/store.py:280-287.

Problems

• The PR is incomplete for the retrieval-count contract described in its body. A repository-wide search finds the only current increment at plugins/memory/holographic/store.py:284; FactRetriever.search, probe, related, reason, and _score_facts_by_vector return results without incrementing at plugins/memory/holographic/retrieval.py:112, :190, :258, :336, and :479.
• No regression test is included. Existing list tests in tests/plugins/memory/test_holographic_store.py invoke list_facts() but do not assert retrieval_count.

Suggested changes

• Centralize ID-based count bumps on MemoryStore, apply it consistently to every retrieval result path, and specify the behavior for both facts in a contradiction pair.
• Add persistence-focused tests for list retrieval, empty results, and each retrieval strategy.
