 * In-flight build coalescing wrapper.
 *
 * @remarks
 * `ParallelBuildExecutor` allows concurrent builds but does not dedupe identical
 * options. Multiple callers (route import, browser bundles, HMR) can hit the
 * same Rolldown request before disk or import caches warm. This wrapper shares
 * one inner `build()` promise per dedupe key until it settles.
 *
 * Wrap route-module and browser-hmr profiles only; server-entry stays serialized.
