feat(registry): complete ATLAS-WP-0002 T02, T03, T06

T02: remove inherited capability.infotech.repo-template and template consumer
docs (statehub-register, template-validation-checklist); add
capability.infotech.config-surface-atlas and rewrite capabilities.yaml.

T03: seed 4 configuration surfaces (state-hub api-config, ops-warden
routing-catalog, reuse-surface federation-sources, ops-bridge tunnel-config)
with registry/indexes/surfaces.yaml; source-linked, no values, secret deps by
reference.

T06: add tools/validate_registry.py (schema + index gate), Makefile (make
validate), and .github/workflows/validate.yml (GitHub + Gitea Actions);
document in stack-and-commands. Verified malformed entries are rejected.

+# ops-bridge SSH tunnel configuration
+
+ops-bridge maintains reverse SSH tunnels that expose the State Hub API and MCP
+endpoints to remote machines (the remote port map: State Hub API `:18000`, MCP
+`:18001`). This surface maps that tunnel configuration as **infra-state**.
+
+- **Source of truth:** the `ops-bridge` repo tunnel config; SSH certs are a secret
+  reference (`depends_on_secret`), signed by ops-warden, never stored here.
+- **Relation:** exposes `surface.infotech.state-hub.api-config` to remote workers.
+- **Mutability:** deploy-time — tunnel changes are brought up via `bridge up`.
