README.md: remove reference to Replier

[nelsam]

As of a685e84, the Replier no longer exists. Including it in the README is confusing. This updates the README to reference the modern Handler type.

Code Review

This pull request updates the example handler signature in the README.md to return a result and an error directly, rather than using a Replier. The review feedback correctly notes that the surrounding explanatory text in the README should also be updated to reflect this change.

Pull request overview

Updates the project README to reflect the current server-side API by removing the obsolete Replier reference and documenting the direct-return Handler shape used by HandlerServer/Serve.

Changes:

• Reworded the HandlerServer + Serve section to describe direct-return request handling.
• Updated the server example handler signature and return style to match the modern Handler type.

Suppressed comments (2)

README.md:144

• This example comment still refers to “reply”, but the Handler API is now direct-return. Updating the wording will keep the example consistent with the API.

		// Decode params, do work, reply with a typed result.

README.md:149

• In the direct-return Handler contract, returning a non-nil error for a notification fails the connection. As written, an unknown notification method would close the connection; the example should drop unknown notifications and only return ErrMethodNotFound for calls (similar to MethodNotFoundHandler).

	default:
		// Answer unknown calls with the standard error.
		return nil, jsonrpc2.ErrMethodNotFound
	}
