deps: libvcs 0.30.0 -> 0.33.0 (test performance improved)

# Problem

Git, Subversion, and Mercurial repositories are unnecessarily reinitialized for each test via libvcs' pytest plugin.

- We're not utilizing session-based scoping.
  - A single initial repo could be created, then copied to [`tmp_path`](https://docs.pytest.org/en/8.3.x/how-to/tmp_path.html#the-tmp-path-fixture) using [`shutil.copytree`](https://docs.python.org/3/library/shutil.html#shutil.copytree) ([source](https://github.com/python/cpython/blob/v3.13.0/Lib/shutil.py#L550-L605)).
