Code Review
This pull request transitions the Vite dev-server dependency optimization configuration from Esbuild to Rolldown, removing the zoneless parameter and introducing rolldownOptions. Feedback highlights a critical issue in the new load hook where virtual modules and query parameters/hashes in module IDs are not handled, which could lead to build failures or skipped compilation. A code suggestion is provided to clean the module IDs before matching and transforming.

…Vite config Vite now uses Rolldown as the underlying engine to optimize dependencies, rendering `optimizeDeps.esbuildOptions` deprecated. This commit refactors the Vite dev-server config in `@angular/build` to use `optimizeDeps.rolldownOptions` instead. It also updates the custom dependency optimization plugin from the esbuild-specific format to a native Rolldown plugin using the `load` hook, and aligns browser target lowering by pushing `es2016` when Zone.js is present (since Rolldown lacks esbuild-style feature-support flags).
