Short description of what this resolves

Moves the light GitHub Actions jobs from ubuntu-latest to ubuntu-slim, the single-CPU container runner (fewer preinstalled tools, no Docker, 15-minute job limit).

Proposed changes

Switched to ubuntu-slim:

• labeler.yml (triage): actions/labeler is a Node action
• spellcheck.yml (spellcheck): cspell-action is a Node action
• test.yml (lint): checkout, setup-node, npm ci, npm run lint

Left on ubuntu-latest:

• publish.yml: any edit makes Super-Linter run zizmor on the file, and it fails on the existing use-trusted-publishing and cache-poisoning findings. Moving to npm trusted publishing is a separate change.
• codeql-analysis.yml: CodeQL analysis is CPU and memory heavy
• ossf-scorecard.yml: ossf/scorecard-action is a Docker container action, which ubuntu-slim cannot run
• sync-labels.yml: micnncim/action-label-syncer is a Docker container action
• super-linter.yml: Super-Linter runs as a Docker image
• test.yml (build): OS/Node matrix that pairs with windows-latest, and the matrix.os != 'ubuntu-latest' condition depends on the label
• website.yml: full Astro/Starlight build with full git history, which risks the 15-minute limit on a single CPU

What changed in this PR

Moves four lightweight GitHub Actions jobs to ubuntu-slim, while leaving heavier and Docker-dependent workflows on their existing runners.

Changes:

• Switches PR labeling, spellchecking, linting, and package publishing to ubuntu-slim.
• Leaves job steps and the test build matrix unchanged.

File	Description
.github/​workflows/​test.yml	Moves only the lint job to ubuntu-slim.
.github/​workflows/​spellcheck.yml	Moves spellchecking to ubuntu-slim.
.github/​workflows/​publish.yml	Moves the build-and-publish job to ubuntu-slim.
.github/​workflows/​labeler.yml	Moves PR label triage to ubuntu-slim.

_{Review effort: Balanced}

The red Lint Code Base run on 719030c is the push run. Super-Linter only lints the files changed in that one push, and that push was the commit reverting publish.yml. So zizmor reported the existing findings in publish.yml (use-trusted-publishing, cache-poisoning), which this PR doesn't change.

The pull_request run diffs against main and passed. Re-running the push run would fail the same way. Once this is squash-merged, publish.yml won't be in the diff, so the run on main won't be affected.
