Add Python build configuration and packaging setup

[Copilot]

The project lacked standard Python packaging infrastructure, requiring manual dependency installation and preventing pip-based workflows.

Changes

Build Configuration

• requirements.txt - declares requests dependency
• setup.py - enables pip install -e . with package metadata
• requirements-dev.txt - adds pytest, flake8, black, mypy for development
• MANIFEST.in - excludes database files from distributions

Package Structure

• app/__init__.py - makes app a discoverable package for setuptools

Docker & Ignores

• Dockerfile - uses requirements.txt for better layer caching
• .gitignore - excludes __pycache__, *.egg-info, dist/, build/, virtual environments

Usage

# Install project
pip install -e .

# Install with dev dependencies
pip install -r requirements-dev.txt

# Build Docker image (now caches dependency layer)
docker build -t binance-trader .

Dependencies verified against GitHub Advisory Database - no vulnerabilities found.
