feat(tooling): Add pyproject.toml for consolidated Python tool configuration (#741)

Consolidate Python tool configurations into a single pyproject.toml file
while preserving existing code formatting standards.

Key improvements:
- Single source of truth for tool configurations
- Dynamic dependency loading from requirements.txt files
- Pytest pythonpath configuration enables running `pytest` directly
- No code reformatting required - matches existing standards

Technical changes:
- Created pyproject.toml with:
  - Black: line-length=88 (default, matches existing formatting)
  - isort: profile=black, line-length=88
  - Pylint: migrated all settings from .pylintrc (max-line-length=120)
  - Pytest: pythonpath=["."] fixes import resolution
- Removed .pylintrc (configuration moved to pyproject.toml)

Benefits:
- Run `pytest` directly without `python -m pytest` workaround
- All tool configs in one standardized location
- Modern Python packaging standards (PEP 517/518)
- No configuration duplication
