Provide a way to apply quick fixes/refactorings/code actions in a bulk automated fashion

Currently, we have several quick fixes and refactorings. Some of these are generally to help reorganize your codebase/fix issues, some are more to migrate from JS to TS more easily, and some are to more-easily opt in to a more strongly-typed version of TypeScript.

The problem here is that these quick fixes/refactorings can become painful when manually applied. Sometimes we want to apply them en masse - altoghether. But perhaps the way I see this as is something that could be applied granularly (individually), altogether at once, or in a one-at-a-time but nonetheless automated fashion (supervised).

Some prior art here we may want to look at for inspiration are jscodeshift.

まず、issue で提案されている一括、きめ細かな適用、および監督下での適用モードを確認し、その後、先行例として jscodeshift と比較します。既存の quick fixes と refactorings を調査する前に、具体的なスコープ、エントリーポイント、完了基準を定義してください。
