Subject: [PATCH] fix: report plugin coverage instead of the tests module

The e2e step ran -coverpkg=./... from inside tests/, so it only ever
instrumented the tests module and the upload filter then dropped every
line. The codecov job also had no checkout and pulled artifacts without
a name, so the *.out glob matched nothing.

Scope coverpkg to the plugin module, check the repo out before
uploading, strip the module prefix with awk like jobs does, and fail the
job when the merged summary holds no plugin blocks.
