v1.5.0

Changed

• The init_experiment, run_experiment, and log_experiment tools are now revealed to the agent only while autoresearch mode is active, instead of being callable in every session. Outside autoresearch mode the tools are absent from the LLM's schema and system prompt, so the agent can no longer self-start a research loop — entry is via /autoresearch or resuming a session with an existing autoresearch.jsonl.
