Meter-gated removal (7 consecutive zero-usage windows reached). Deletes:
- MCP tools: create_workstream, list_workstreams, update_workstream,
update_workstream_status
- MCP resource: state://workstreams/{topic_slug}
- Dead helpers: _LEGACY_MCP_* maps, _legacy_mcp_deprecation,
_meter_legacy_mcp, _attach_legacy_deprecation, _update_workplan_legacy_impl
TOOLS.md keeps a retired→preferred migration map (per backlog). Removed the
now-dead STATEHUB_MCP_LEGACY_METER guard in conftest. Retargeted the
create_workplan error-skip test to the preferred tool; dropped alias-only tests.
Staged on branch state-wp-0070-legacy-retirement — do not merge until the 7th
documented zero-usage window is captured.

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.

Replace the fixed 15s TTL on GET /state/summary with per-table revision
watermarks, stale-while-revalidate background refresh, and a progress-tail
section split. SQLAlchemy write hooks invalidate core or progress sections
on mutation. Adds tests, benchmark script, and operator docs.
- Migration t7o8p9q0r1s2: indexes on tasks.status, tasks(workstream_id,status),
workstreams.status, sbom_snapshots(repo_id,snapshot_at)
- workplan-index: 30 s TTL cache + ?refresh param (4171 ms → 16 ms on hit)
- /state/summary: 15 s TTL cache, bypassed on Cache-Control: no-cache
- /topics/: noload(workstreams, decisions, progress_events) (2382 ms → 115 ms)
- /domains/: noload(topics, repos, goals) (2252 ms → 39 ms)
- /repos/: noload(goals) (2222 ms → 599 ms first / fast on repeat)
- conftest: reset TTL caches between tests to prevent bleed-through
