Subject: [PATCH] ci: only run buildcache on dev/master pushes

The push trigger had a path filter but no branch filter, so any PR-branch push
touching those paths (e.g. a dependabot rebase pulling in setup-deps changes)
launched the full fresh buildcache matrix concurrently with CI.

- restrict the push trigger to branches [dev, master]
- frees runners for CI; the cache still refreshes via cron and on dev/master
