🧹 Improve type safety in RPC transfer lists

[zknpr]

🎯 What:

• Replaced any[] with Transferable[] in Transfer class and RPC interfaces (MessageDispatcher, ResponseDispatcher).
• Updated WorkerPort interface and connectWorkerPort implementation to correctly type and pass transfer arguments.
• Fixed a bug in src/workerFactory.ts where the transfer argument was ignored in the postMessage implementation.
• Added a new test case in tests/unit/rpc.test.ts to verify Transfer wrapper functionality and transfer list handling.

💡 Why:

• Improves type safety by preventing arbitrary objects from being passed as transferables, which would cause runtime errors.
• Ensures zero-copy transfers actually work by fixing the bug where the transfer list was dropped.
• Makes the code more maintainable and self-documenting regarding what data is expected.

✅ Verification:

• Ran npm test to verify all tests pass, including the new RPC tests.
• Verified that Transferable type is available and correct in the project environment.
• Verified that postMessage implementations in both Browser and Node environments support the transfer list argument.

✨ Result:

• Stronger type guarantees for RPC operations.
• Fixed zero-copy transfer mechanism.
