act_runner runs as SYSTEM and does not have plain 'python' in PATH; use py.exe launcher (-3.11) to bootstrap the venv when missing. The production venv at F:\CI\python\venv normally already exists, so the bootstrap is just a fallback. Also align coverage threshold to 80% (raised in A5, see AGENTS.md).
The runner's act_runner runs as SYSTEM, which only sees the Machine PATH.
Host has Python 3.14 installed at C:\Program Files\Python314\; once that
path is added to the machine PATH (one-time admin op) the simple
Get-Command python lookup works without network downloads.
The act_runner service account doesn't have python in PATH. Delegating
to actions/setup-python@v5 which downloads/caches Python 3.11 reliably.
Also bump timeout-minutes 15 -> 20 to absorb first-run pip install.
Gitea Actions only scans .gitea/workflows/ and .github/workflows/. The
file under gitea/workflows/ (no leading dot) was never picked up. Other
files in gitea/workflows/ remain as templates copied into consumer repos.
