search-with-proof: probe harness (3.2) and agent worker (group 5)

Probe runs each oracle toy pair with a real demo and two gaming demos, records
image facts, RSS and disk, fails loudly if isolation is unavailable; dispatchable
as an AX task. Worker: reason step without tools, explore tool loop whose run tool
goes through the sandbox with a scrubbed env (model key absent), spend reserved
before each call. Host probe: 5/5 real demos demonstrated, 10/10 gaming demos
inconclusive. 89 tests.
