Follow-up to the ported status fix:
- `tui_gateway/contracts/tools_mcp_plugins.py::McpRuntimeStatus` is a
closed wire enum; `mcp.servers.status` would raise `ContractViolation`
on the new `lazy` value. Declare it and regenerate the TS/OpenRPC
contract files.
- `ui-tui` session panel: an unknown status fell through to the red
`failed` branch; render `lazy` with its cached tool count (inline
branch, no component extraction).
- Two invariant tests, both red on origin/main: the real discovery path
yields `status: lazy` with the cached tool count and a summary without
`failed` (eager control stays `configured`, live control stays
`connected`); a lazy-only run neither warns nor re-arms the startup
retry, while a configured-only run still does.
- Document the per-server `lazy` key (undocumented until now) in
`cli-config.yaml.example`, the MCP config reference and the MCP guide.
