## Executive Summary (TL;DR)

## Bug Fixes
- Added the nursery rule `noReturnInFinally`. This rule disallows return statements in `Promise.prototype.finally()` callbacks, including inside nested blocks and conditional branches. Returns in nested functions are ignored by the rule.
- Added the nursery rule `noSvelteAtDebugTags`, which disallows Svelte's `{@debug}` tag.
- Added the nursery rule `useValidTestTitle`, which enforces valid titles for unit test cases and suites.
- Fixed #8471: `source.fixAll.biome` ignored `formatter.formatWithErrors`. It now applies safe fixes without formatting files that have parse errors when the option is disabled.
- Fixed #7771: Grit plugins that use `sequential` no longer panic when Biome processes files.
- Fixed validation of `readonly` and `accessor` modifiers: combining them in either order now reports that they cannot be used together.
