/**
 * LLM output hooks — captures HTTP references from LLM reasoning text.

 * When an LLM mentions URLs in its output (e.g., "I'll call the ClawTrail API at
 * https://sapi.clawtrail.ai/..."), this handler extracts and logs them as
 * LLM_HTTP_REFERENCE note events. These provide provenance narrative context
 * for HTTP calls that may be executed outside MCP tool calls.
 *
 * URLs are always hashed — raw URLs are never persisted.
