feat: script sol.rooms/fetch/memory ops + research execute integration

- script: sol.rooms() against live Tuwunel, sol.fetch() with allowlist
  enforcement (allowed domain succeeds, blocked domain caught),
  sol.memory.set/get round-trip against OpenSearch
- research: single-task execute against Mistral API with real Matrix
  room, verifies session persistence lifecycle
