/**
 * Creates a Vite plugin that forces the specified packages into the entry chunk,
 * preventing them from being split into separate chunk files during code splitting.
 *
 * This works by:
 * 1. Injecting a static import of each package at the top of the entry module,
 *    making the entry chunk directly depend on the package.
 * 2. Marking all resolved modules belonging to the packages with
 *    `moduleSideEffects: 'no-treeshake'`, which prevents Rolldown from
 *    tree-shaking the injected import away (e.g. when the package declares
 *    `"sideEffects": false` in its package.json).
 *
 * Together this ensures the packages stay in the entry chunk even when they
 * are only imported (directly or indirectly) by lazily loaded components.
 *
 * @param packages - Array of package names (e.g. `['@dynatrace/strato-node-graph']`).
 *   Both bare specifiers and subpath imports are matched.
