# 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 stage the store-layout tree with the SAME script local
# builds use (clients/decky/scripts/package.sh) — the plugin's file list lives in exactly ONE
# place, so a file added there (bin/, assets/, controller_config/, …) can never be silently
# missing from the published build. (Hand-assembling the zip here is how the shipped plugin
# lost the shortcut artwork + Steam Input layout for a while.) CI only adds `update.json` on
# top: the {channel, manifest} pointer the plugin's self-update check polls.
#
# SELF-UPDATE (no Decky store): alongside the zip we also publish a tiny per-channel
# `manifest.json` ({version, artifact=<immutable per-version zip URL>, sha256}). The installed
# plugin polls it (main.py check_update), and the frontend drives Decky's own install RPC to
# apply a newer build. See clients/decky/README.md "Updating".
#
# REGISTRY_TOKEN: repo Actions secret, a PAT with write:package scope (shared with deb/rpm/docker).
