Subject: [PATCH] ci: stop running the matrix twice per pull request

The push and pull_request triggers both matched every branch, so each PR
kicked off two identical runs of lint, the three-OS test matrix and the
soulfind e2e job. Push now only covers master; branches are covered by the
pull_request trigger. Adds a concurrency group so a follow-up push cancels
the superseded run instead of queueing behind it.
