Two things kept CI from being green, and neither was the code.
First, GitHub Actions was DISABLED at the repository level. The workflows
registered fine and simply never ran -- `gh api .../actions/permissions`
returned {"enabled": false}. Now enabled.
Second, once it ran, shellcheck failed on a file that is clean locally:
SC2236 in PSD/zin3/python/run_temperature_system.sh. `language: system` hooks
use whatever is on PATH, and Ubuntu's packaged shellcheck is not the 0.11.0
this machine has, so the build went red for a difference in tool version
rather than in the code. That is the failure mode testsAndMisc pins tools to
avoid, so the workflow now installs shellcheck v0.11.0 and verifies its
SHA256 -- checked here first: the digest matches and the archive really does
unpack to shellcheck-v0.11.0/shellcheck.
The `! -z` -> `-n` fix is applied too. Pinning stops the next version drift;
fixing the code means this instance is right under either version.
