The default route table when boot is called with no routingSpec/children:
/ → main content, /files/<path> → the file router, else not-found.
Re-expressed with path templates (SANDBOX_ROUTING_SPEC §7); the file path
surfaces under the * wildcard. The catch-all stays a raw RegExp — the
escape hatch — so it anchors .+ (a non-empty path) exactly as before.
