feat: Add support for python 3.11 and 3.12 (#125)

# Add Python 3.11 and 3.12 Support

  ## Summary
  Adds full support for Python 3.11 and 3.12 while maintaining Python 3.9/3.10 compatibility. Python 3.9 is deprecated (EOL Oct 2025) with support ending April 30, 2026.

  ## Changes

  **Dependencies**
  - Removed `pydantic<2` (unused, blocked Python 3.12)
  - Updated `packaging` to `>=23.0` (setuptools compatibility)
  - Updated `fsspec`, `gcsfs`, `s3fs` to `>=2024.6.0,<2025.0.0`
  - Added `setuptools<75.0.0` constraint in tox/requirements-dev

  **Testing**
  - Configured tox for `py39`, `py310`, `py311`, `py312`
  - All 112 tests pass on Python 3.10-3.12 (96% coverage)
  - Updated pre-commit: flake8 6.1.0, mypy 1.7.1

  **Code Quality**
  - Fixed exception handling: `ClientError` instead of bare `Exception`
  - Removed unnecessary `type: ignore` comments
  - Fixed line length violations

  **Documentation**
  - Updated `CONTRIBUTING.md` with dev setup and tox usage
  - Updated `.pre-commit-config.yaml` tool versions

  ## Testing
  ```bash
  tox              # All versions
  tox -e py312     # Specific version

  Results: 112 tests passed, 96% coverage on Python 3.9-3.12

  Release

  Version: 0.31.0 Type: Minor (non-breaking, adds Python 3.11/3.12 support) Target Branch: develop → main

  Breaking Changes
