Treat U+30A0 & U+30FB in Katakana Block as CJK (#​16796 by @​tats-u)

Prettier doesn't treat U+30A0 & U+30FB as Japanese. U+30FB is commonly used in Japanese to represent the delimitation of first and last names of non-Japanese people or “and”. The following “C言語・C++・Go・Rust” means “C language & C++ & Go & Rust” in Japanese.

<!-- Input (--prose-wrap=never) -->

C言

・
C++
・
Go
・
Rust

<!-- Prettier 3.4.1 -->
C言語・ C++ ・ Go ・ Rust

<!-- Prettier 3.4.2 -->
C言語・C++・Go・Rust

U+30A0 can be used as the replacement of the - in non-Japanese names (e.g. “Saint-Saëns” (Charles Camille Saint-Saëns) can be represented as “サン゠サーンス” in Japanese), but substituted by ASCII hyphen (U+002D) or U+FF1D (full width hyphen) in many cases (e.g. “サン=サーンス” or “サン＝サーンス”).

Fix comments print on class methods with decorators (#​16891 by @​fisker)

// Input
class A {
  @​decorator
  /** 
   * The method description
   *
  */
  async method(foo: Foo, bar: Bar) {
    console.log(foo);
  }
}

// Prettier 3.4.1
class A {
  @​decorator
  async /**
   * The method description
   *
   */
  method(foo: Foo, bar: Bar) {
    console.log(foo);
  }
}

// Prettier 3.4.2
class A {
  @​decorator
  /**
   * The method description
   *
   */
  async method(foo: Foo, bar: Bar) {
    console.log(foo);
  }
}

Fix non-idempotent formatting (#​16899 by @​seiyab)

This bug fix is not language-specific. You may see similar change in any languages. This fixes regression in 3.4.0 so change caused by it should yield same formatting as 3.3.3.

// Input
<div>
  foo
  <span>longlonglonglonglonglonglonglonglonglonglonglonglonglonglongl foo</span>
  , abc
</div>;

// Prettier 3.4.1 (first)
<div>
  foo
  <span>
    longlonglonglonglonglonglonglonglonglonglonglonglonglonglongl foo
  </span>, abc
</div>;

// Prettier 3.4.1 (second)
<div>
  foo
  <span>longlonglonglonglonglonglonglonglonglonglonglonglonglonglongl foo</span>
  , abc
</div>;

// Prettier 3.4.2
<div>
  foo
  <span>longlonglonglonglonglonglonglonglonglonglonglonglonglonglongl foo</span>
  , abc
</div>;
