Adds serverFunctions.serialization, a module that sets the codec for server-function payloads on both the client and the server. It is the counterpart of SolidStart's serialization.plugins option.

solid({ serverFunctions: { serialization: './src/serialization.ts' } })

// src/serialization.ts
import { createPlugin } from '@solidjs/web/serialization';
export default { plugins: [ObjectIdPlugin] };

Changes

• The default export is the JSONCodecOptions object from @solidjs/web/serialization: plugins, disabledFeatures, depthLimit and serializeErrorStacks.
• A bare plugin array is shorthand for { plugins }. A SolidStart serialization.plugins module works unchanged.
• Every compiled "use server" module imports the file and passes it as codec to configureServerFunctionsClient or configureServerFunctionsServer. This uses the same appended configure call the custom endpoint already uses.
• The generated virtual:solid-server-function-handler also imports it, so the dev middleware and the production handler have the codec before the first dispatch.
• The path resolves against the Vite root. A missing file is a config-time error, like configure. Both options now share one resolve helper.
• Without the option, compiled output is byte-identical to before.
• README: a new serialization section under options.serverFunctions.

Notes

• The runtime replaces the whole codec setting on each configure call. The docs say not to also pass codec elsewhere.
• The SSR hydration payload is not affected. renderToStream takes its own plugins option. SolidStart behaves the same way.
• Feature (for disabledFeatures) is imported from seroval. Re-exporting it from @solidjs/web/serialization would need a change in solidjs/solid.

Testing

• New src/server-functions/serialization.test.ts. It creates a project with a Money class and a seroval plugin, calls the function through the generated handler on @solidjs/web rc.16, and decodes a real Money on the client side. It covers the object export, the array export, no option, and a missing path. It fails without the change.
• vitest run: 40 of 40 pass.
• A production client build keeps the plugin and the codec configuration in the bundle.
• The examples/start-ssr browser e2e suite was not run.
