fix: bump vulnerable deps and drop EOL Python 3.9

- requests >= 2.33.0 (was >=2.31.0) — fixes insecure temp file reuse (GHSA)
- pytest ^9.0.3 (was ^8.4.1) — fixes vulnerable tmpdir handling (GHSA)
- pygments >= 2.20.0 (dev dep) — fixes ReDoS via GUID regex (GHSA)
- python >= 3.10 (was >=3.9) — 3.9 reached EOL Oct 2025; CI already tests 3.12 only
- ruff target-version updated from py39 → py310 to match
