Wraps copr-cli submit/watch/download-build with per-chroot log
dumping as collapsible ::group:: blocks. Moves the logic previously
living at .gitea/scripts/copr-build.sh in helexa/cortex into a
reusable action so every consumer gets live log visibility and
consistent failure diagnostics.
Inputs: project, srpm (glob OK), copr-config (secret).
