Pull request overview

This PR introduces a unified --install flag that streamlines the installation process by installing the dashlights binary to an appropriate PATH location, configuring the shell prompt, and automatically detecting and setting up AI agent hooks for Claude Code and Cursor in a single command.

Key changes:

• Added --install flag for complete installation (binary + prompt + detected AI agents)
• Implemented smart binary installation logic that respects existing locations, skips non-preferred directories, and falls back to ~/.local/bin with automatic PATH configuration
• Automatic detection and installation of AI agent hooks when .claude or .cursor directories are present
