/** * @fileOverview: Automatic project indexing with smart file detection and cloud synchronization * @module: AutomaticIndexer * @keyFunctions: * - autoDetectAndIndex(): Auto-detect current project and start indexing * - indexProject(): Index a project with smart ignore patterns * - watchProject(): Set up file system watching for automatic updates * - getIndexingStatus(): Monitor indexing progress and status * @dependencies: * - TreeSitterProcessor: AST parsing and symbol extraction * - LocalProjectManager: Local project state management * - ProjectIdentifier: Project detection and identification * - apiClient: Cloud service synchronization * - globby: File pattern matching and discovery * @context: Provides automatic project indexing with intelligent file detection, cloud synchronization, and file system watching.
