Add zizmor workflow SAST from the updated template

[CybotTM]

Adds the standalone zizmor.yml the netresearch/.github go template now carries (netresearch/.github#327) — GitHub Actions static analysis, report-only (SARIF to code scanning), minimal permissions. Pure new-file add.

Changes:

• Introduces a new .github/workflows/zizmor.yml workflow that runs on push and pull_request to main.

[CybotTM]

Superseded by #636 (commit c1b6349), which landed the same .github/workflows/zizmor.yml from the go template during the org-wide scanner rollout. The file is on the default branch already, so this PR is now a no-op and its branch would only conflict.

Closing rather than merging. Nothing is lost: the zizmor workflow, the shared .github/zizmor.yml config and the GITLEAKS_LICENSE removal are all live on the default branch — verified across all 57 repos in the rollout.
