MIME-Version: 1.0

Content-Transfer-Encoding: 8bit

* eslint: `explicit-function-return-type`

* eslint: `no-unnecessary-condition`

* eslint: `eslint-disable-next-line`

* eslint: `no-unused-vars`

* eslint: `comma-dangle`

* eslint: `import/order`

* cleanup: unnecessary non-null assertion

* cleanup: `IActivity`に`actor`は常に存在するようなので

* cleanup: unnecessary `as`

* cleanup: unnecessary `Promise.resolve`

* cleanup

* refactor: `String.prototype.match()`である必要がない部分をよりシンプルな書き方に変更

* refactor: よりよい型定義

* refactor: よりよい型定義

- `LdSignature`の`normalize`メソッドでの使われ方から、
	- `data`引数の型定義を`any`から`JsonLdDocument`へ修正
	- `getLoader`メソッドの返り値の型定義の一部を`any`から`RemoteDocument`へ修正
		- `contextUrl`が不正な値（`null`）となっていたことが判明したため`undefined`へ修正
		- `document`の型と合わせるために`CONTEXTS`の型定義の一部を`unknown`から`JsonLd`へ修正
			- とりあえず`satisfies`を使用
		- `document`の型と合わせるために`fetchDocument`メソッドの返り値の型定義の一部を`unknown`から`JsonLd`へ修正
			- どうしようもなく`as`を使用

* refactor: 型ガードを使うことでnon-null assertionをやめた

* refactor: non-null assertionをやめた

`.filter()`で行っている型ガードなどの文脈から、より適しているだろうと思われる書き方に変更した。

* refactor: 型ガードを使うことで`as`をやめた

* refactor: `as`をやめた

* refactor: よりよい型定義

- `id`は`null`とのunionになっていたが、`null`を渡している場面はなかった
	- またおそらくこのメソッドは`IOrderedCollection`を返すため、そちらに合わせて`null`とのunionをやめた
		- `IOrderedCollection`とはまだ型に相違がある
- `totalItems`をコメントや使われ方を元に`number`へ推論

* refactor: `for-of` -> `Array.prototype.map`

* refactor: `delete`演算子を使わない形に
