# Build the punktfunk Decky Loader plugin (Gaming-Mode QAM launcher) into a distribution zip
# and publish it to Gitea's GENERIC package registry, giving Decky's "install from URL" a
# stable link. On tags the zip is ALSO attached to the Gitea release.
#
#   PUT/GET  https://git.unom.io/api/packages/unom/generic/punktfunk-decky/<version>/punktfunk.zip
#
# The plugin backend is PURE PYTHON (clients/decky/main.py — no compiled binary), so we do NOT
# need the Decky CLI (which requires Docker + rust-nightly only to compile native backends).
# We build the frontend with pnpm and assemble the store-layout zip by hand:
#
#   punktfunk.zip
#     punktfunk/                  <- single top-level dir == plugin.json "name"
#       plugin.json   [required]
#       package.json  [required]
#       main.py       [required: python backend]
#       dist/index.js [required: rollup output]
#       README.md     (recommended)
#       LICENSE       [required by the plugin store]
#
# REGISTRY_TOKEN: repo Actions secret, a PAT with write:package scope (shared with deb/rpm/docker).
