v2.5.2 — Safer CSV exports

Highlights

• CSV exports (export_csv() / export()) are now safer by default: values that spreadsheet apps like Excel, Google Sheets, or LibreOffice could misinterpret as formulas are automatically escaped when the file is opened.
• New sanitize option (defaults to True) — pass sanitize=False to export_csv() if you need the previous raw export behavior.

What's Changed

• chore: fix ruff import-sort lint drift in #50
• fix: sanitize CSV formula injection in export_csv (CWE-1236) in #52
