Wire hub-core progress legacy-meter hook for GET /progress/?workstream_id.
MCP list_tasks, list_blocked_tasks, and list_human_interventions now call
REST with workplan_id only so internal clients do not inflate legacy usage.
Add legacy_compat helper and Deprecation headers when callers filter
/tasks, /decisions, /token-events, or /execution/launch-requests with
workstream_id. Preferred workplan_id filters are unchanged. Route removal
remains gated on legacy-meter zero-usage windows.
Adds preferred workplan REST/event surfaces, legacy-meter telemetry and weekly review summaries, documentation/dashboard terminology updates, dashboard API loading fixes, and close-out sync for STATE-WP-0052 and STATE-WP-0054.
