Add minimal CI

[jagmarques]

Adds the first CI workflow. The repo had none.

What it does:

• Runs the pytest suite (15 tests) on Python 3.11 and 3.12
• Compiles scripts/ as a fast syntax check
• A ci-ok gate job that needs the test matrix

No package install step. The plugin ships as hook scripts with no pyproject
and no third-party runtime deps, so CI installs pytest and nothing else. No
ruff step either, since the repo carries no lint config to honor.

Tests run with python -m pytest so the repo root lands on sys.path and the
suite can import scripts.asqav_hook. The bare pytest console script cannot,
and one test fails under it.

Triggers on push and pull_request to main.

Proof of work

Local run before push (Python 3.11.15):

$ python -m pytest tests/ -q
...............
15 passed in 21.18s

Live CI on this PR, run https://github.com/jagmarques/asqav-claude-code/actions/runs/29021952576 (conclusion success):

$ gh pr checks 2
ci-ok        pass  2s
test (3.11)  pass  34s
test (3.12)  pass  9s

Both matrix legs installed pytest 9.1.1 and reported the full suite green:

test (3.11): 15 passed in 0.85s
test (3.12): 15 passed in 0.87s
