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.
