Minor Changes

• Lower let/const to var in the build output for faster QuickJS parsing. The SWC transform-block-scoping pass is added to both the background and main-thread layers (on top of the existing target baseline), and rspack output.environment.const is set to false so bundler-generated runtime code also uses var. (#2755)

• Support a function form for output.filename.bundle. (#2701)

  output.filename.bundle now accepts a function (context: { lazyBundle: boolean; entryName?: string; platform: string }) => string in addition to a string. The function is called once for the main bundle (lazyBundle: false) and once for the lazy bundles (lazyBundle: true), so a single config can control both the main bundle filename and the lazy bundle filename — without a dedicated lazyBundle field or a custom plugin.

  import { execSync } from 'node:child_process'
  
  import { defineConfig } from '@lynx-js/rspeedy'
  
  const gitHash = execSync('git rev-parse --short HEAD').toString().trim()
  
  export default defineConfig({
    output: {
      filename: {
        bundle: ({ lazyBundle, platform }) =>
          lazyBundle
            ? `my-lazy-bundles/[name].[fullhash]-${gitHash}.bundle`
            : `[name].${platform}.bundle`,
      },
    },
  })

• Support Rsbuild v2 and Rspack v2 in the React Rsbuild plugin, including the new CSS and JavaScript rule structure, Rspack-only refresh and CSS extraction plugins, top-level splitChunks handling, and Rspeedy profile configuration. (#2603)

• Express the SWC compilation baseline through env (a high targets plus an explicit include transform list) instead of jsc.target. The emitted build output is unchanged for existing projects. (#2748)

  Because env and jsc.target are mutually exclusive in SWC, tools.swc.jsc.target is no longer accepted and now throws a clear error. To downlevel specific syntax, add the corresponding transforms to tools.swc.env.include instead — they extend the base/background baseline (the main thread keeps its fixed es2019 baseline, matching the previous jsc.target behavior).

Patch Changes

• Enrich the "Unknown property" validation error of pluginReactLynx to point users at pluginLynxConfig when they are trying to set a Lynx config. (#2796)
