Adds standard project hygiene files and pyproject metadata:

Scaffolding files added:

• .gitattributes - line-ending normalization
• .pre-commit-config.yaml - pre-commit hooks (trailing-whitespace, end-of-file-fixer, check-yaml, check-toml, check-added-large-files, detect-private-key, ruff, ruff-format)
• .github/dependabot.yml - automated dependency updates
• .github/ISSUE_TEMPLATE/bug_report.yml - bug report template
• .github/ISSUE_TEMPLATE/feature_request.yml - feature request template
• CHANGELOG.md - changelog
• SECURITY.md - security policy
• LICENSE - MIT license

pyproject.toml enhancements:

• Added �uthors field
• Added keywords for PyPI discoverability
• Added comprehensive classifiers (Python versions, OS, license, etc.)
• Added [project.urls] with repository link
• Updated license format to SPDX-style {text = "MIT"}

.gitignore hardening:

• Added Python cache files (*.pyc, *.egg-info/)
• Added build artifacts (dist/, �uild/, *.egg)
• Added OS files (.DS_Store, Thumbs.db)
• Added merge conflict artifacts (*.orig, .BACKUP., etc.)
• Added local database files

Note: A separate branch ix/pages-deploy-only contains the GitHub Pages workflow file but cannot be pushed via this token (lacks workflow scope). That workflow file will need to be created manually in the GitHub UI or with a token that has the workflow scope.
