fix: update black line-length to 88 and reformat codebase

- Update pyproject.toml to use black's default line-length of 88
- This matches what the CI workflow expects (black --check without args)
- Reformat all Python files to comply with the new line length
- This will prevent CI failures due to formatting discrepancies
