Typed base schema meta

[emmatown]

Unsure if I want to ship this.

Big open question around the all method:

• Should it exist?
• Should it have the "ignore the index signature from the Types type" behaviour so that it only accepts known type names?
• Should it be called all? Other ideas:
  • strict
  • any
  • named

PR Overview

This PR introduces stronger TypeScript typings for the extension functions by parameterizing the schema metadata with a generic map of named types. It also adds a new "all" method to BaseSchemaMeta and updates the type signatures of schema wrapping helper functions.

The 'all' method lacks an else branch to handle the case where 'getType(name as string)' does not match any of the known GraphQL type checks. Consider adding an error throw for unsupported types.

[Copilot]

[nitpick] The repeated explicit cast 'name as string' might indicate that the 'getType' function's type signature could be refined to accept a more specific type, thereby reducing the need for such casts.

Suggested change

	const graphQLType = getType(name as string);
	const graphQLType = getType(name);
