claude --grep "search term" 

# The CLI now tests ripgrep availability on first use
# Falls back gracefully if ripgrep is not available

Details:

• Automatic detection of system ripgrep installation
• Built-in ripgrep binary as fallback option
• Performance telemetry for ripgrep availability
• Configurable search modes (system vs built-in)
