_emit_progress_event strips legacy workstream_id from POST /progress/
payloads. Task and decision side-effect events now set workplan_id
explicitly so automatic progress logging stays workplan-first.
Legacy MCP tools and the workstreams resource now return _deprecation payloads
pointing to workplan-named replacements. get_domain_summary uses workplan-first
prose and exposes a workplans key alongside the legacy workstreams field.
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.
