# Build one plugin zip per Jellyfin generation into ./artifacts.
#
# Jellyfin binds a plugin to the exact API it was compiled against, and 10.11 changed
# signatures that still compile but fail at runtime. So each generation gets its own DLL
# (see the TargetFrameworks comment in Jellyfin.Plugin.SRFPlay.csproj) and its own
# manifest entry. Jellyfin installs the highest version whose targetAbi is <= the server
# version, so the flavour code is folded into the version to keep them apart:
#
#   net8.0  -> targetAbi 10.9.0.0   (Jellyfin 10.9 / 10.10)   code 9
#   net9.0  -> targetAbi 10.11.0.0  (Jellyfin 10.11)          code 11
#   net10.0 -> targetAbi 12.0.0.0   (Jellyfin 12)             code 12
#
# Usage: build-plugins.sh <version-format>
#   <version-format> is a printf format that receives the flavour code, e.g.
#     "1.2.0.%d"             -> 1.2.0.9, 1.2.0.11, 1.2.0.12         (release)
#     "1.0.20260924.204%02d" -> 1.0.20260924.20409, ...20411, ...20412 (nightly)
#
# Writes artifacts/builds.tsv with one line per zip: version, targetAbi, zip path, md5.
