ci: Split CI checks by changed area

[dcramer]

CI now runs as focused, path-gated jobs instead of one monolithic workflow. Pull requests run only the relevant release, skills, lint, typecheck, test, build, docs, and dashboard e2e checks, while pushes still run the full set and package artifacts.

The workflow also centralizes Node/pnpm setup in a local composite action, adds concurrency cancellation for stale PR runs, limits Playwright installation to dashboard e2e, and uses a single ci / required aggregator so branch protection can accept intentionally skipped jobs without losing failure signal.

After this lands, branch protection should require ci / required instead of the old monolithic CI job.

Cancelled jobs fail required check

Medium Severity

The ci / required job treats cancelled the same as failure, while the workflow enables cancel-in-progress for pull requests. When a newer push cancels an in-flight run, sibling jobs often end as cancelled, so the aggregator can report a failed required status even though a newer run is still valid.
