Run Python exercise scripts

Run Python script from exercise directory via uv run

Educational environments where students run exercise scripts without CLI friction.

• · Script name/path, exercise number (e.g., '2.3'), or currently open file

• · Script execution output (stdout/stderr)
• · Exit code

• · uv (Python package runner)
• · Python

• · uv installed
• · Script has if __name__ == '__main__': block OR path provided
• · ExerciseX.Y/src/ directory structure if exercise number given

• · Script not found in ExerciseX.Y/src/ — lists available scripts and asks which to run
• · No if __name__ == '__main__': block — cannot auto-detect runnable script
• · Dependencies missing — uv error (user must install via uv add)

• · Auto-discovery from exercise directory structure
• · Fallback to IDE open file detection
• · Passes through user arguments (no hardcoding)
