build(deps): update requests to 2.33.0

[james-d-mitchell]

Update Requests from 2.32.5 to 2.33.0 in uv.lock to address Dependabot alert #33 (CVE-2026-25645: insecure temporary file reuse in extract_zipped_paths()). requirements.txt already pins 2.33.0. Only the Requests version and distribution metadata change.

Validation:

• uv lock --check --offline and git diff --check passed.
• Installed the locked documentation dependencies in an isolated temporary environment; uv pip check passed.
• Temporary smoke checks passed for distinct extracted paths, preservation of preexisting files, existing/missing path handling, and Sphinx request preparation.
• Both pre-commit hook stages completed: codespell passed; other hooks had no applicable files.
• No C++ rebuild or full pytest/doctest run for this lockfile-only change.

AI assistance: OpenAI Codex investigated the alert, prepared the dependency update, and ran the validation checks.
