Fix Windows tag passing: use env var instead of step outputs

Step outputs via GITHUB_OUTPUT are unreliable with act runner on
Windows (BOM encoding issues). Replaced with job-level env var
RELEASE_TAG set directly from inputs.tag, and checkout ref also
uses inputs.tag directly. Eliminated the Determine tag step
entirely — no intermediate output needed.
