feat: add GiteaClient repo variable methods and parallelize pytest-cov

Add get_repo_variable() and set_repo_variable() to GiteaClient for
reading/writing Gitea Actions repository variables. Both handle 404
gracefully (get returns None, set creates via POST). Includes 7 new
tests with 100% coverage.

Speed up pytest-cov by adding -n auto (xdist parallelization) and
removing -v (verbose output). Reduces runtime from ~13s to ~6s on
16-core machines. test-unit stays serial (xdist adds overhead for
fast mocked tests).
