# Assembles the plugin release zip and its .sha256 sidecar from a Release build.
#
# The layout is the one the OpenAC launcher's installer accepts:
# - plugin.json and the entry DLL sit at the zip root;
# - only these extensions: .dll .pdb .json .xml .txt .md .png .jpg .jpeg .ttf .otf;
# - no runtimes/ folder, and no AcDream assembly beside the plugin's own;
# - the plugin.json published as its own release asset is the same file as the
#   zip's copy;
# - the sidecar is `sha256sum`'s line: the hash, two spaces, the zip's name.
# Asset names are <id>-<version>.zip and <id>-<version>.zip.sha256.
