feat(node-ci): optional runner input for self-hosted runners

[WomB0ComB0]

Adds an optional runner input (default ubuntu-latest) to the reusable node-ci.yml, so a caller can route the job onto a self-hosted runner via runner: self-hosted.

Backward-compatible — omitting the input keeps ubuntu-latest, so every existing consumer is unchanged.

Why: when GitHub-hosted Actions minutes are exhausted org-wide, every hosted job fails at startup (zero steps). A self-hosted runner sidesteps that. Consumers wire the input to a repo/org variable (e.g. runner: ${{ vars.CI_RUNS_ON || 'ubuntu-latest' }}) so it toggles without editing workflows.

Consumed by resq-software/research (see its companion ci/self-hosted-runner-option PR). Same pattern can extend to security-scan.yml as a follow-up.
