Start warming turns with callback-form run_asyncHEADv0.2.0main

Drive the warm turn from the luv timer with callback run_async, caching
only its termination, and abandon with a nonjoining close. Removes native
job polling. Adds binding-check.lua, a real-binding check against local HTTP
fixtures, to mise run check.

Requires a Pantograph host with callback-form run_async.
