feat(consistency): coordination hygiene checks and MCP workplan_id aliases

Add C-25..C-30 fix-consistency checks for blocked-workplan inbox sweeps,
stale unread triage, workplan ID prefix/collision lint, and SCOPE freshness.
Extend brief generation and get_domain_summary with inbox hygiene warnings.
Complete workplan_id aliases on remaining MCP tools and retry transient
_api_get failures to reduce false stale-reference errors under load.
