Complete ops-hub Inter-Hub bootstrap and close bootstrap workplans.

Extract bootstrap logic into src/ops_hub/bootstrap.py with dry-run support,
public hub discovery, and unit tests. Update the gate probe to accept public
hub listing (200 or 401), document dev commands and architecture, and archive
finished OPS-WP-0001 and OPS-WP-0002 workplans.

 ## Current State
 
-- Status: active bootstrap.
-- Implementation: no executable source tree yet; first real workplan is seeded
-  in `workplans/OPS-WP-0002-interhub-extension-bootstrap.md`.
-- Live Inter-Hub production gate: `/api/v2/hubs` still returned `404` on
-  2026-06-06, so supported API bootstrap is not yet available in production.
+- Status: production bootstrap complete (2026-07-07).
+- Implementation: Python package under `src/ops_hub/`, operator scripts, seeds,
+  tests, and Makefile targets for gate probe and attended bootstrap.
+- Inter-Hub: `ops-hub` hub, active manifest, seed widgets, and first
+  `ops-endpoint-verified` event are live in production.
