Upgrade to ESLint v10 once plugin ecosystem catches up

[wizzomafizzo]

Dependabot tried to bump @eslint/js to v10 in #50. ESLint 10.8.0 is now available, but the upgrade remains blocked by two plugins whose latest stable releases still cap peer support at ESLint 9.

Remaining upstream blockers

• eslint-plugin-react — 7.37.5 supports only ^3 || ^4 || ^5 || ^6 || ^7 || ^8 || ^9.7
• eslint-plugin-jsx-a11y — 6.10.2 supports only ^3 || ^4 || ^5 || ^6 || ^7 || ^8 || ^9

Do not force these peer ranges. Wait for stable releases declaring ESLint 10 support.

Compatible prerequisites

• eslint-plugin-react-hooks 7.1.1 supports ESLint 10
• @tanstack/eslint-plugin-query 5.101.4 supports ESLint 10
• eslint-plugin-react-refresh 0.5.3 supports ESLint 10
• @typescript-eslint/* 8.58+ supports ESLint 10
• eslint-plugin-import-x 4.16+ supports ESLint 10
• eslint-plugin-testing-library 7.16+ supports ESLint 10
• eslint-config-prettier 10.1+ supports ESLint 10
• eslint-import-resolver-typescript 4.4+ supports ESLint 10
• @vitest/eslint-plugin 1.6.24 is available as the maintained replacement for abandoned eslint-plugin-vitest

Project preparation

• Replace eslint-plugin-vitest with @vitest/eslint-plugin
• Bump eslint-plugin-react-hooks to 7.1.1
• Bump eslint-plugin-react-refresh to 0.5.3

Final ESLint 10 upgrade

Once both upstream blockers release compatible versions:

1. Land any remaining project preparation above.
2. Bump eslint, @eslint/js, eslint-plugin-react, and eslint-plugin-jsx-a11y together.
3. Run clean install, lint, typecheck, tests, formatting, build, and dependency audit.
4. Close this issue when the ESLint 10 change is merged.

Re-checked current package/peer dependency state.

Still blocked for ESLint v10:

• eslint-plugin-react@7.37.5 still caps peer deps at ESLint 9 (^3 || ^4 || ^5 || ^6 || ^7 || ^8 || ^9.7).
• eslint-plugin-jsx-a11y@6.10.2 still caps peer deps at ESLint 9 (^3 || ^4 || ^5 || ^6 || ^7 || ^8 || ^9).
• eslint-plugin-vitest@0.5.4 still caps peer deps at ESLint 9 and is still used by eslint.config.js. Migrating to @vitest/eslint-plugin is still the likely path there.

No longer blocked:

• eslint-plugin-react-hooks@7.1.1 supports ESLint 10.
• @tanstack/eslint-plugin-query@5.100.14 supports ESLint 10.
• eslint-plugin-react-refresh@0.5.2 supports ESLint 10 and the project is already on that range.

Verdict: issue is still valid, but blocker list is now smaller/staler than original description.
