feat(workers): add createWorkerRPC for type-safe module worker communication

[deny-dz]

Summary

This PR introduces createWorkerRPC to @solid-primitives/workers:

• Modern Module Web Worker Support: Unlike existing string-blob inline workers, createWorkerRPC seamlessly works with external TypeScript/ESM module workers created via bundlers (new URL('./worker.ts', import.meta.url) in Vite, Webpack, and SolidStart).
• Type-Safe RPC Proxy: Wraps workers in a typed TypeScript proxy that converts worker method signatures into Promise-returning RPC calls (mathWorker.compute(...)).
• Correlation IDs & Timeouts: Generates unique request IDs to safely match async responses, with customizable call timeouts (default 30s).
• Automatic Transferables: Automatically detects ArrayBuffer and ArrayBufferView arguments to transfer ownership without cloning.
• Lifecycle Cleanup: Automatically terminates the worker and rejects in-flight promises upon Solid owner cleanup.

Changes

• packages/workers/src/rpc.ts: Core createWorkerRPC proxy implementation.
• packages/workers/src/index.ts: Re-export createWorkerRPC and Promisify types.
• packages/workers/test/rpc.test.ts: Vitest test suite.
• .changeset/workers-typed-rpc.md: Minor changeset.
