This repo still carried the inline pipeline from before the config
extension, including the droparea SSH upload that predates
/build/upload. That step asked for a droparea_ssh_password secret which
no longer exists, so every run failed before reaching the publish.
The marker config gets the same pipeline every other TIC-80 repo gets,
and the artifacts go through /build/upload and /build/publish.
The Makefile keeps its ci-upload target and DROPAREA_* variables; they
are now unused by CI and can go in a separate pass.
