Generate and use a project index for quick codebase understanding in new sessions. Scans the workspace, extracts exported symbols, writes .claude-index/index.md plus config, and injects a Google-style Clean Code Guidelines section into CLAUDE.md. Use when the user says "explore the project", "generate index", "regenerate index", "更新索引", "生成索引", or presses Ctrl+I.
