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

[Copilot]

This PR migrates the project from ESLint to oxlint, a high-performance Rust-based linter, using the shared @eggjs/oxlint-config configuration.

Changes Made

Dependencies

• Removed: eslint and eslint-config-egg dependencies
• Added: oxlint (^1.11.0) and @eggjs/oxlint-config (^1.0.0) as dev dependencies

Configuration

• Replaced .eslintrc with .oxlintrc.json that extends from the shared @eggjs/oxlint-config
• Migrated ignore patterns from .eslintignore to the ignorePatterns field in oxlint config
• Removed old ESLint configuration files (.eslintrc, .eslintignore)

Scripts

• Updated lint script from eslint src test --ext .ts to npx oxlint src test
• Simplified pretest script to remove --fix flag (oxlint handles fixes differently)

Documentation

• Updated references in CONTRIBUTING.md and site/docs/community/CONTRIBUTING.md from "Eslint" to "oxlint"

Benefits

• Performance: oxlint is significantly faster than ESLint, improving development workflow
• Consistency: Uses the shared @eggjs/oxlint-config for consistent linting rules across egg projects
• Maintainability: Configuration is now much cleaner and easier to maintain by extending from the shared config
• Compatibility: Maintains similar rule coverage with TypeScript, import, promise, unicorn, and other plugin equivalents
• Future-proof: oxlint is actively developed and optimized for modern JavaScript/TypeScript projects

Testing

The migration has been tested and verified to:

• ✅ Load configuration correctly using extends from @eggjs/oxlint-config
• ✅ Find linting issues in TypeScript files
• ✅ Work with the npm run lint script
• ✅ Maintain existing ignore patterns
• ✅ Preserve linting behavior for CI/CD workflows

The new setup finds similar issues to the previous ESLint configuration while running significantly faster.

@copilot should extends from @eggjs/oxlint-config

Updated the configuration to extend from @eggjs/oxlint-config instead of manually defining all rules. This makes the configuration much cleaner and easier to maintain while preserving the project-specific ignore patterns. Commit: 9ccb845
