Alias tests monkeypatch _get/_post but _meter_legacy_mcp uses _client()
directly, so every pytest run recorded real usage and reset zero-window
retirement streaks. STATEHUB_MCP_LEGACY_METER=off skips metering; set in
tests/conftest.py. Verified meter counts flat across the alias suite.

T03: MCP alias retirement gate was unstartable — deprecation notices existed
but no mcp:* interfaces were ever registered or metered. Add
_meter_legacy_mcp() posting /legacy-meter/usage (kind mcp_tool, component
state-hub.mcp) from create_workstream, list_workstreams, update_workstream,
update_workstream_status, and state://workstreams/{topic_slug}; register all
five phase-3 backlog keys so zero-window streaks accrue from today.
T04: trace residual POST /progress/ workstream_id (3 calls/8h, unknown) to
.custodian-brief.md labelling workplans "workstream_id:"; brief generator now
prints "workplan_id:". Briefs refresh on each repo's next fix-consistency run.

Add retire_legacy_route() helper and convert CRUD, dependency, and
execution intent legacy routes to 410 Gone while preserving final-call
legacy-meter attribution. Update tests, retirement backlog, and close
STATE-WP-0075 with handoff to STATE-WP-0070 T02 and STATE-WP-0073 T04.
Add X-StateHub-Component to fix-consistency and other State Hub REST callers for
legacy-meter attribution. Archive STATE-WP-0069; open STATE-WP-0070 for
meter-gated phase-2 retirement. Task POST bodies use workplan_id only.
