Cancelling a build only killed the running build process; the synchronous
preparation phases — most notably a multi-minute Docker image build, but also
the Gradle-volume preparation — ran to completion and kept the concurrency
slot occupied, so the next queued build stayed PENDING for a long time.
Build runners now report every auxiliary process through an onAuxProcess sink
(GitCommandRunner gained an onProcess hook), and the executor registers them
like the build process, so cancellation terminates whatever is currently
running. Measured on vm4006: cancel to next-build-running is ~3s in the
normal case; the unit test covers the aux-phase case.

certbot removed ssl-dhparams.pem from its repository, so the managed-nginx
startup failed with HTTP 404 on fresh installations (the legacy script only
kept working through its year-old state-dir cache). The RFC 7919 ffdhe2048
parameters are now a classpath resource; the download seam and
NginxConfigFiles.DH_PARAMS_URL are gone.
