Phase Agent Yield & Advancement Reliability

Phase agents can now declare a bounded wait with --status yield when delegating to a background job, so finishing work is no longer recorded as abandonment. The advancement sweep gains a durable once-per-edge idempotency guard keyed on the predecessor’s identity, preventing the same phase edge from firing multiple times in a single tick. Two supporting fixes round out the release: the Linear webhook monitor now detects 401 authentication failures via route-comparison against the GitHub control, and connected replicas report the schema bundle they actually loaded rather than a version string that may not reflect what’s in memory.
