Patch Changes

#8583 83be210 Thanks @dyc3! - Added the new nursery rule useVueValidTemplateRoot.

This rule validates only root-level <template> elements in Vue single-file components. If the <template> has a src attribute, it must be empty. Otherwise, it must contain content.

Invalid examples:
```
<template src="./foo.html">content</template>
```
```
<template></template>
```
Valid examples:
```
<template>content</template>
```
```
<template src="./foo.html"></template>
```
#8586 df8fe06 Thanks @dyc3! - Added a new nursery rule useVueConsistentVBindStyle. Enforces consistent v-bind style (:prop shorthand vs v-bind:prop longhand). Default prefers shorthand; configurable via rule options.
#8587 9a8c98d Thanks @dyc3! - Added the rule useVueVForKey, which enforces that any element using v-for also specifies a key.

Invalid
```
<li v-for="item in items">{{ item }}</li>
```
Valid
```
<li v-for="item in items" :key="item.id">{{ item }}</li>
```
#8586 df8fe06 Thanks @dyc3! - Added a new nursery rule useVueConsistentVOnStyle. Enforces consistent v-on style (@event shorthand vs v-on:event longhand). Default prefers shorthand; configurable via rule options.
#8583 83be210 Thanks @dyc3! - Added the new nursery rule useVueValidVOnce. Enforces that usages of the v-once directive in Vue.js SFC are valid.
```

<div v-once />


<div v-once:aaa />
<div v-once.bbb />
<div v-once="ccc" />
```
#8498 d80fa41 Thanks @tt-a1i! - Fixed #8494. Extended noUndeclaredEnvVars to support bracket notation (process.env["VAR"], import.meta.env["VAR"]), Bun runtime (Bun.env.VAR, Bun.env["VAR"]), and Deno runtime (Deno.env.get("VAR")).
#8509 574a909 Thanks @ematipico! - Added support for parsing and formatting the Svelte {#await} syntax, when html.experimentalFullSupportEnabled is set to true.
```
-{#await promise  then name }
+{#await promise then name}

-{:catch    name}
+{:catch name}

{/await}
```
#8316 d64e92d Thanks @washbin! - Added the new nursery rule noMultiAssign. This rule helps to prevent multiple chained assignments.

For example, the following code triggers because there are two assignment expressions in the same statement.
```
const a = (b = 0);
```
#8592 a5f59cd Thanks @Netail! - Added the nursery rule useUniqueInputFieldNames. Require fields within an input object to be unique.

Invalid:
```
query A($x: Int, $x: Int) {
  field
}
```
#8524 17a6156 Thanks @JacquesLeupin! - Fixed #8488: Relative plugin paths are now resolved from the configuration file directory, including when configurations are merged (e.g. extends: "//").
#8655 3260ec9 Thanks @JacquesLeupin! - Fixed #8636: Biome's CSS formatter now breaks comma-separated declaration values at top-level commas when wrapping.

#8537 cc3e851 Thanks @dibashthapa! - Fixed #8491: Resolved false positive errors for safe boolean expressions. There are still pending fixes. Head to #8491 (comment) for more details

This new change will check for safe boolean expressions in variable declarations.

For example,

Valid:

let isOne = 1;
let isPositiveNumber = number > 0;

return (
  <div>
    {" "}
    {isOne && "One"} {isPositiveNumber && "Is positive"}
  </div>
);

Invalid:

let emptyStr = "";
let isZero = 0;

return (
  <div>
    {emptyStr && "Empty String"} {isZero && "Number is zero"}{" "}
  </div>
);

#8511 16a9036 Thanks @ematipico! - Improved the diagnostics of the rules useSortedClasses and noUnnecessaryConditions. The diagnostics now state that these rules are a work in progress and link to the relevant GitHub issue.
#8521 a704be9 Thanks @ToBinio! - Added the nursery rule useVueConsistentDefinePropsDeclaration, which enforces consistent defineProps declaration style.

Invalid

<script setup lang="ts">
const props = defineProps({
  kind: { type: String },
});
</script>

Valid

<script setup lang="ts">
const props = defineProps<{
  kind: string;
}>();
</script>

#8595 7c85bf0 Thanks @dyc3! - Fixed #8584: The HTML formatter will preserve whitespace after some elements and embedded expressions, which more closely aligns with Prettier's behavior.
```
- <h1>Hello, {framework}and Svelte!</h1>
+ <h1>Hello, {framework} and Svelte!</h1>
```
#8598 5e85d43 Thanks @Netail! - Added the nursery rule useUniqueFieldDefinitionNames. Require all fields of a type to be unique.

Invalid:
```
type SomeObject {
  foo: String
  foo: String
}
```
#8495 b573d14 Thanks @taga3s! - Fixed #8405: noMisusedPromises now emits warnings/errors when a function returns union types such as T | Promise<T> which is used in conditionals.
```
const a = (): boolean | Promise<boolean> => Promise.resolve(true);
if (a()) {
} // Now correctly flagged
```
#8632 0be7d12 Thanks @Bertie690! - The documentation & rule sources for lint/complexity/noBannedTypes have been updated to fix a few oversights.

In addition to some general typo fixes:
- The rule now recommends Record<keyof any, never> instead of Record<string, never> (the latter of which incorrectly allows symbol-keyed properties).
- The rule mentions an alternate method to enforce object emptiness involving unique symbol-based guards used by type-fest and many other packages:
```
declare const mySym: unique symbol;

// Since this type's only property is an unexported `unique symbol`, nothing that imports it can specify any properties directly
// (as far as excess property checks go)
export type EmptyObject = { [mySym]?: never };
export type IsEmptyObject<T> = T extends EmptyObject ? true : false;
```
The rule's listed sources have been updated as well to reflect the original source rule (ban-types) having been split into 3 separate rules circa April 2024.
#8580 a3a1ad2 Thanks @taga3s! - Added the nursery rule noBeforeInteractiveScriptOutsideDocument to the Next.js domain. This rule prevents usage of next/script's beforeInteractive strategy outside of pages/_document.js.
#8493 5fc24f4 Thanks @ematipico! - Added support for parsing and formatting the Svelte {#each} syntax, when html.experimentalFullSupportEnabled is set to true.
```
- {#each items   as item  }
+ {#each items as item}

{/each}
```
#8546 0196c0e Thanks @Zaczero! - Hardened union static-member type flattening in edge cases (e.g. unions containing unknown or inferred expression types). This keeps inference conservative and avoids unstable type growth in node = node.parent-style loops.
#8569 1022c76 Thanks @ematipico! - Fixed an issue where the Biome HTML parser would emit a parse error when certain keywords are inside the text of HTML tags.
#8606 f50723b Thanks @dyc3! - Fixed #8563: fixed a bounds check on bogus regex literals that caused panics when doing type inference
#7410 ab9af9a Thanks @sgarcialaguna! - Added the new nursery rule noJsxPropsBind. This rule disallows .bind(), arrow functions, or function expressions in JSX props.

Invalid:
```
<Foo onClick={() => console.log("Hello!")}></Foo>
```
#8523 5f22f1c Thanks @ematipico! - Improved the diagnostics of nursery rules. Added a message to diagnostics emitted by nursery rules, so that users are aware of nature of nursery rules.
#8571 03666fd Thanks @dyc3! - Improved the performance of noRedeclare by eliminating string allocations
#8591 9dd9ca7 Thanks @Netail! - Added the nursery rule useUniqueArgumentNames. Enforce unique arguments for GraphQL fields & directives.

Invalid:
```
query {
  field(arg1: "value", arg1: "value")
}
```
#8521 a704be9 Thanks @ToBinio! - Update useVueDefineMacrosOrder to only run on
