Replace all mutable action/reusable-workflow tag references in the workflows with the immutable commit SHA they currently resolve to, keeping the original version as a trailing comment for readability and future bumps. This hardens the CI supply chain against tag-mutation attacks (per GitHub's hardening guidance). Covers third-party actions (actions/*, astral-sh/setup-uv, codecov/codecov-action, peter-evans/create-pull-request, mikepenz/release-changelog-builder-action, github/codeql-action, crate-ci/typos) and the NVIDIA-NeMo/FW-CI-templates reusable workflows. Local ./.github reusable-workflow references are unchanged (not tags). Signed-off-by: svcnemo-autobot <svcnemo-autobot@nvidia.com>

Background
Workflow steps referenced third-party actions and reusable workflows by mutable tags (e.g.
@v6), which are vulnerable to tag-mutation supply-chain attacks. GitHub's hardening guidance recommends pinning to immutable commit SHAs.What changed
