Pull request overview
This PR strengthens RuleTester conformance by applying rule-provided fixes to test case code and asserting the result matches the test case’s output (including correct handling of output: null / missing output). To support this, it introduces a native applyFixes binding and threads fix data through the JS diagnostics used by RuleTester.
Changes:
- Add
RuleTesterassertions for fixed output vs expectedoutput, and plumbfixesthrough diagnostics. - Introduce a NAPI
applyFixesfunction (Rust) to apply serialized fix groups to source text. - Update
RuleTesterunit tests and conformance snapshots to reflect the new fix-validation behavior.

`RuleTester` test that fixes provided by the rule match what's expected in the test case - that code after applying fixes matches the test case's `output` property. This reveals some bugs - 12 ESLint + 62 `eslint-plugin-stylistic` conformance tests are failing after this PR. These bugs are fixed in later PRs in this stack.

…ing in ESLint compat mode (#19094) Oxlint's behavior when applying two fixes which are directly adjacent to each other is different from ESLint. * ESLint considers adjacent fixes to be overlapping and only applies the 1st. * Oxlint considers adjacent fixes NOT to be overlapping and applies them both. Alter this behavior in `RuleTester` to follow ESLint's logic when `eslintCompat` option is used. This fixes the rest of the failing conformance tests which were broken by #19091. This PR does not alter the logic for Oxlint itself. I think we should consider doing that, but it needs discussion, so I'll open a separate issue for it.
