feat: machine binding and version enforcement

migration 017 adds machine_id to agents table
middleware validates X-Machine-ID header on authed routes
agent client sends machine ID with requests
MIN_AGENT_VERSION config defaults 0.1.22
version utils added for comparison

blocks config copying attacks via hardware fingerprint
old agents get 426 upgrade required
breaking: <0.1.22 agents rejected
