LaunchLens CLI - Quick Startup Idea Validation

Usage:
  launchlens <idea>                    Validate a single idea
  launchlens --file <path>              Validate ideas from file (one per line)
  launchlens --json <idea>              Output in JSON format
  launchlens --roast <idea>             Enable roast mode (extra harsh)
  launchlens --detailed <idea>          Detailed analysis with market scores
  launchlens --model <model> <idea>     Use specific AI model
  launchlens --help                     Show this help

Configuration Commands:
  launchlens config set <key> <value>   Set configuration value
  launchlens config get <key>           Get configuration value
  launchlens config list                List all configuration

Examples:
  launchlens "AI-powered todo app for developers"
  launchlens --json "marketplace for local tutors"
  launchlens --roast "uber for dogs"
  launchlens --detailed "AI code review tool"
  launchlens --model gpt-4 "AI code review tool"
  launchlens --file ideas.txt
  launchlens config set openai-api-key sk-...
  launchlens config set model gpt-4
  launchlens config list

Configuration Keys:
  openai-api-key       OpenAI API key for GPT analysis (REQUIRED)
  perplexity-api-key   Perplexity API key for real competitor search (RECOMMENDED)
                       Without this, you'll get placeholder competitor data
  model                AI model to use (gpt-4, gpt-4-turbo-preview, gpt-3.5-turbo, gpt-3.5-turbo-16k)

Environment Variables (fallback if not configured):
  OPENAI_API_KEY       OpenAI API key
  PERPLEXITY_API_KEY   Perplexity API key

Note: Get your Perplexity key at https://www.perplexity.ai/settings/api for accurate competitor data
