The orgs agent-configs/internal/agents (plus mirror owners), the
operators team in agents and agent-configs, the pull-mirrors,
internal/docs, internal/knowledge (public, README-seeded) and the
agent-configs org avatar are one set per forge. hive-c0re ensured them in
its boot sweep, as the core admin, and only on the hive co-located with
the forge container.
swarm-controller now reconciles them at start and every 5 minutes
(forge/objects.rs: observe -> pure plan -> apply). A failed object logs
a warn line plus a pass summary and is retried next tick. create_repo
ensures the agent-configs org and its operators team first, so a config
repo's merge gate never depends on the periodic pass having run.
hive-c0re drops ensure_org, SEEDED_ORGS, ensure_mirrors/ensure_mirror_repo,
ensure_operators_team, ensure_shared_docs_repo, ensure_knowledge_repo/
set_repo_public, seed_readme, ensure_config_org_avatar and the one-shot
knowledge::remove_webhook cleanup, with their now-unused helpers.
nix: the mirror list moves from the hive-c0re unit
(HYPERHIVE_FORGE_MIRRORS) to the swarm-controller unit
(SWARM_CONTROLLER_FORGE_MIRRORS), with an eval warning when mirrors are
declared on a host that runs no controller. c0re.orgAvatarPng is renamed
to deploy.swarm-controller.configOrgAvatarPng.
