Add project setup: dependencies, config, and package scaffolding

- requirements.txt with all core dependencies (streamlit, binance, ta, anthropic, praw, etc.)
- .env.example template for all required API keys
- .gitignore covering secrets, caches, db files, and logs
- config.py loading env vars with trading defaults and signal weights
- tests/conftest.py with sys.path fix for imports
- Empty __init__.py files for tests, data, agents, engine, dashboard, scheduler packages
