/**
 * Serializes a bundle in which the graph's modules are placed inside a single
 * segment definer -- `__registerSegment(0, function (moduleId) { switch (...) })`
 * -- so that each module's `__d(...)` call runs lazily on first require instead
 * of eagerly at startup. Polyfills and the require runtime (pre-modules) and the
 * run-module calls (append scripts) are emitted eagerly, as usual.
 *
 * This is the OSS equivalent of the metro-buck "plain bundle with switch"
 * output, gated behind `serializer.unstable_lazilyDefineModules`. Unlike
 * `baseJSBundle` + `bundleToString`, which keep modules as independently
 * addressable top-level `__d(...)` statements, the switch form wraps them all in
 * one function -- so the code and source map must be assembled together (a
 * `BundleBuilder`), rather than via the flat index-map path which assumes the
 * plain layout.
 *
 * The structured graph is untouched, so deltas and HMR (which address modules
 * individually via `hmrJSBundle`) are unaffected: an HMR update is still a
 * top-level `__d(...)` that shadows the switch branch. The runtime materialises
 * a not-yet-required module on demand via its segment definer (see
 * `ensureModuleRegistered` in the require polyfill), so Fast Refresh keeps
 * working with behaviour identical to an eager bundle.
