Fix the pre-commit backlog (363 → 0 findings)

Follow-up to #250, which added actionlint with the shellcheck backlog suppressed
via -shellcheck= and -ignore. This fixes the underlying issues and removes both
suppressions, so pre-commit run --all-files passes with the hook fully enabled.

First: main is currently red

Before touching the backlog, actionlint failed even with the suppressions in
place. #243 (ROCm, merged after #250) added runs-on: rocm without declaring the
label in .github/actionlint.yaml. pre-commit is not a required check yet, so
nothing blocked it. Adding rocm to the label list unbreaks main on its own.

Verification

• All 9 hooks pass with both suppressions removed.
• Extracted all 171 run: blocks from the parsed YAML: 0 bash syntax errors.
  Same 171 before and after, so no step was dropped. before was already
  syntax-clean, so this confirms preservation rather than a fix.
• Executed all 61 changed blocks before-and-after with cluster tools stubbed,
  comparing stdout plus the summary/output/env files: 60 byte-identical. The 20
  that first appeared to differ carried only bash's own error text with shifted
  line numbers.
• The 1 remaining difference is oc adm … -n "${NAMESPACE}", visible only because
  the harness left NAMESPACE unset. Unreachable in practice: the input is
  required: true, and the line directly above already runs
  kubectl create namespace "$NAMESPACE" quoted, so an empty value fails a line
  earlier.
