chore(format): apply black code formatter to all Python files

[Techikrish]

• Run black --line-length=100 on all source and test files
• Reformatted 20 files to match Black formatting standards
• 1 file left unchanged (already compliant)
• Fixes CI/CD black formatting check failures
• Ensures code style consistency across project

This aligns all code with Black's opinionated formatting style, making the codebase consistent and passing CI/CD checks.
