search_knowledge and get_entity_knowledge only ever returned a ts_headline
snippet/short headline — enough to find a note, not enough to act on it.
Add get_knowledge_content(slug), mirroring the web UI's
/api/v1/knowledge/content/{id}, so the agent can read a document/
investigation/runbook's full markdown body once it knows which one it
needs. upsert_knowledge already covered the write side. Cross-referenced
all three tool descriptions so the agent discovers the full-read path.
