refactor: rename factory/ → supervisor/, factory-poll → supervisor-poll

The supervisor agent was confusingly named "factory" (same as the
project). Rename directory, script, log, lock, status, and escalation
files. Update all references across scripts and docs.

FACTORY_ROOT env var unchanged (refers to project root, not agent).
