What's Changed

💥 Breaking Changes

Core API Refactoring (@eslint-react/core)

• Performed a large-scale flattening refactor of the core package's internal structure, merging modules previously scattered across subdirectories like component/, function/, hook/, semantic/, and api/ into the root directory.
• Renamed several core APIs:
  • isReactAPI → isAPI
  • isReactAPICall → isAPICall
  • isInitializedFromReact → isAPIFromReact
  • isInitializedFromReactNative → isAPIFromReactNative
  • ComponentDetectionHint → FunctionComponentDetectionHint
  • ComponentFlag → FunctionComponentFlag
  • getComponentCollector → getFunctionComponentCollector
  • getComponentCollectorLegacy → getClassComponentCollector
• Migrated type utilities type-is, type-name, and type-variant from eslint-plugin-react-x to @eslint-react/core.
• Updated the Toolkit interface in @eslint-react/kit to reflect the naming changes above.

Removed Rules

• @eslint-react/no-redundant-should-component-update: This rule, along with its documentation and tests, has been removed from eslint-plugin-react-x and all configuration presets (all, x, recommended, strict, etc.).
• debug/class-component: This debug rule has been removed from eslint-plugin-react-debug and the debug/all configuration.

Class Component Support Deprecation

• All Class Component-related detection functions in the core package (such as isClassComponent, isPureComponent, and various lifecycle checkers) have been marked as @deprecated, retaining only minimal compatibility support for existing rules.
• Rules in eslint-plugin-react-web-api, including no-leaked-event-listener, no-leaked-interval, and no-leaked-timeout, have removed detection for Class Component lifecycles (componentDidMount / componentWillUnmount) and now only report on Hook Effects (useEffect, etc.).

📝 Documentation

• Added an Examples page (/docs/examples), listing all official example projects and links.
• Removed redundant Overview headings in several places throughout the documentation.
• Updated the migration guide and roadmap.

🏗️ Internal Improvements

• Unified the import style for @typescript-eslint/types across the codebase, merging TSESTree types and AST_NODE_TYPES constants into single-line imports.
• Removed scripts/prepare-release.ts and the accompanying prepare:release npm script.
• Updated dependency versions for esbuild, @eslint/compat, @types/node, undici, etc.
