A local 'dotnet build' leaves agent/*/obj and agent/*/bin full of absolute
host paths. They are gitignored, but the export rsyncs the WORKING TREE, so
.gitignore does not apply and the scrub gate stopped the whole export - which
is what it is for, but it made publication depend on whoever built the agent
last having cleaned up.
Same shape as the stray .env.bak the excludes already document. Note the trap
that follows from it: an --exclude also PROTECTS a path from --delete, so the
copies the first failed run had already placed in the publication tree had to
be removed by hand before the next run could pass.
