Scaffold initial jarvis_glm Python project

[AryaVLcom]

Motivation

• Provide a Windows-friendly Python 3.11+ scaffold for a future Jarvis voice assistant with a minimal, testable CLI and dev tooling.

Description

• Add project metadata and dev tooling configuration in pyproject.toml including pytest, ruff, and mypy settings.
• Implement the jarvis package under src/ with __init__.py, a CLI entry in __main__.py, and a doctor module that collects and formats runtime diagnostics including COMSPEC.
• Add tests and test support in tests/ including conftest.py to insert src on PYTHONPATH and tests/test_doctor.py covering collect_diagnostics, format_diagnostics, and the python -m jarvis doctor invocation.
• Add repository support files: .gitignore, README.md, and .env.example for onboarding.

Testing

• Executed PYTHONPATH=src python -m jarvis doctor which exited with status 0 and printed the diagnostics header and fields successfully.
• Ran pytest -q and all tests passed (3 passed).
