style: improve import formatting and increase line length to 120

Configuration Changes:
- Increase ruff line-length from 100 to 120 characters
- Increase isort line_length to 120 to match
- Set force_grid_wrap = 0 to allow single imports on one line
- Keep vertical hanging indent for multi-line imports

Import Formatting Changes:
- Single imports now use: from module import Item
- Multiple imports use hanging indent with parentheses:
  from module import (
      Item1,
      Item2,
  )

Files Updated:
- pyproject.toml: Updated ruff and isort configuration
- python/rivet_di/__init__.py: Single-line imports
- python/rivet_di/container.py: Single-line imports
- python/rivet_di/decorators.py: Mixed single/multi-line imports
- python/rivet_di/scope.py: Single-line import
- python/rivet_di/_rivet_core.pyi: Single-line imports

This provides cleaner, more readable imports while maintaining consistency
with Black formatting style for multi-line cases.
