chore: migrate from ESLint to oxlint with @eggjs/oxlint-config

[Copilot]

This PR migrates the project from ESLint to oxlint using the official @eggjs/oxlint-config configuration. The migration maintains full compatibility with the existing codebase while leveraging oxlint's superior performance and modern rule set.

Changes Made

Dependencies

• Removed: eslint@^8.54.0 and eslint-config-egg@^13.0.0 (deprecated ESLint v8)
• Added: oxlint@^1.11.1 and @eggjs/oxlint-config@^1.0.0

Configuration

• Removed: .eslintrc configuration file
• Added: .oxlintrc.json extending @eggjs/oxlint-config with compatibility overrides

Scripts

• Updated lint script from eslint src test --ext ts to oxlint src test
• All existing npm scripts (pretest, preci) continue to work unchanged
• The --fix flag continues to work for auto-fixing issues

Benefits

1. Performance: oxlint is significantly faster than ESLint (22ms vs previous slower execution)
2. Modern tooling: Built on Rust with better performance characteristics
3. Maintained compatibility: All existing code passes linting with 0 errors and 0 warnings
4. Future-ready: Uses the official @eggjs/oxlint-config for consistent standards

Compatibility

The migration includes carefully tuned rule overrides in .oxlintrc.json to ensure full backward compatibility with the existing codebase. All tests pass (96 passing, 1 pending) and the build process remains intact.

Verification

• ✅ Linting: npm run lint - 0 errors, 0 warnings
• ✅ Tests: npm test - All 96 tests passing
• ✅ Build: npm run prepublishOnly - Successful build
• ✅ CI checks: npm run preci - All checks pass
