The runtime knows no language: the build makes each served entrypoint executable. For a TypeScript bundle that is <entry>.serve.mjs, which imports the entrypoint and serves what it registered over MCP on stdio through the bundle's own SDK. The build records its launchers on the bundle, and the composer names the launcher where a build wrote one and the entrypoint where it did not, so bundles built before this keep serving until they are rebuilt.
