 * Connection id synthesized by the env-var path. The leading underscore marks

 * zero-config id the YAML loader must adopt when the env-var path is retired.
 *
 * Distinct from the test factories' {@link DEFAULT_CONNECTION_ID} (`"default"`,
 * exported from `tests/factories/runtime.ts`): same constant name, different
 * value, different world. This one is the production env-var synthesis; that
 * one is an arbitrary fixture id. The values differ on purpose — do not unify.
 *
 * Fallback contract: with no CLI args and no env vars, this module produces
 * `connections: { _default: { type: "direct" } }` alongside the
 * always-present `server` block. This yields a config with no service
 * blocks, so only connection-agnostic tools are enabled. When the env-var
 * path is retired, the YAML loader must preserve this connection shape.
