• I have searched the current rule list and found no rules that match my proposal.
• I have read the FAQ and my problem is not listed.

My proposal is suitable for this project

• I believe my proposal would be useful to the broader TypeScript community (meaning it is not a niche proposal).

Description

With the objectLiteralTypeAssertions option turned on, we can suggest code changes to either swap to a type annotation or to use satisfies.

Since these both change TypeScript's behaviour, I thought it would be better to have them as suggestions instead of autofixes.

Fail

const x = { ... } as T;

Pass

const x: T = { ... }; // autofix for variable declarators
const x = { ... } satisfies T; // autofix for TypeScript 4.9+

Additional Info

Happy to open a PR. I've previously implemented this in a Microsoft repo and would like to bring it upstream.
