Add tech-stack-agnostic comprehensive application description

[Copilot]

Created a detailed 1,647-word description of PoRobotStocks that explains functionality, architecture, and features without referencing specific technologies.

Changes

• Added APP_DESCRIPTION.md containing comprehensive application overview covering:
  • Core value proposition: affordable robotics stock analysis (≤$10)
  • Smart discovery across 100+ stocks in 20 robotics categories
  • AI-powered multi-dimensional scoring with buy/hold/sell recommendations
  • Real-time market data integration with historical charts
  • Technical indicators (RSI, MACD, moving averages, volatility)
  • Multi-source sentiment analysis (-1 to +1 scoring)
  • Watchlist management and company fundamentals
  • System health monitoring and diagnostics
  • Resilience patterns (circuit breakers, retries, graceful fallbacks)
  • Incremental data refresh with rate limit compliance
  • Responsive UI with detailed analysis views
  • Testing infrastructure and cloud deployment architecture

Description focuses on what the system does and how it benefits users rather than implementation details, making it suitable for stakeholder communication, onboarding, or high-level technical discussions.
