Add parentheses for nullish coalescing in ternary (#​16391 by @​cdignam-segment)

This change adds clarity to operator precedence.

// Input
foo ? bar ?? foo : baz;
foo ?? bar ? a : b;
a ? b : foo ?? bar;

// Prettier 3.3.2
foo ? bar ?? foo : baz;
foo ?? bar ? a : b;
a ? b : foo ?? bar;

// Prettier 3.3.3
foo ? (bar ?? foo) : baz;
(foo ?? bar) ? a : b;
a ? b : (foo ?? bar);

Add parentheses for decorator expressions (#​16458 by @​y-schneider)

Prevent parentheses around member expressions or tagged template literals from being removed to follow the stricter parsing rules of TypeScript 5.5.

// Input
@​(foo`tagged template`)
class X {}

// Prettier 3.3.2
@​foo`tagged template`
class X {}

// Prettier 3.3.3
@​(foo`tagged template`)
class X {}

Support @let declaration syntax (#​16474 by @​sosukesuzuki)

Adds support for Angular v18 @let declaration syntax.

Please see the following code example. The @let declaration allows you to define local variables within the template:

@​let name = 'Frodo';

<h1>Dashboard for {{name}}</h1>
Hello, {{name}}

For more details, please refer to the excellent blog post by the Angular Team: Introducing @​let in Angular.

We also appreciate the Angular Team for kindly answering our questions to implement this feature.
