# Build the punktfunk Windows HOST as a signed Inno Setup installer and publish it to Gitea's generic
# package registry, so a Windows GPU box can install the streaming host (SYSTEM service + bundled
# pf-vdisplay virtual-display driver + the web management console, run by a scheduled task on a bundled
# bun) from one signed setup.exe. Runs on the self-hosted Windows runner
# (host mode; scripts/ci/setup-windows-runner.ps1) — same MSVC/Windows-SDK/LLVM env as windows.yml.
#
# Why an installer and not MSIX (like the client): the host installs a LocalSystem SCM service that
# CreateProcessAsUserW's into the interactive session for secure-desktop capture, and bundles a
# kernel/IDD driver — neither is expressible in MSIX's sandbox. The real install logic already lives
# in `punktfunk-host service install` (crates/punktfunk-host/src/service.rs); the installer just lays
# the exe down and calls it elevated. Packaging internals: packaging/windows/README.md.
#
# Registry (public reads, unom org): https://git.unom.io/unom/-/packages  (generic group)
#
# Versioning (free-form; not MSIX's 4-part rule) — single project version:
#   vX.Y.Z tag -> X.Y.Z   (THE release; published + stable `latest/` alias + attached to the
#                          unified Gitea Release).
#   main push / dispatch -> 0.3.<run_number>  (canary; `canary/` alias; climbs by run number).
#
# Signing reuses the client's MSIX_CERT_PFX_B64 / MSIX_CERT_PASSWORD secrets (CN=unom). Without them
# an ephemeral self-signed cert is generated and its public .cer published next to the installer
# (import once to LocalMachine\TrustedPublisher). See packaging/windows/pack-host-installer.ps1.
#
# GPU backends: the host builds with --features nvenc,amf-qsv = all three vendors in one installer.
#  - NVENC (NVIDIA, direct SDK): the only link need is nvencodeapi.lib, synthesised from a 2-export
#    .def with llvm-dlltool (no GPU/SDK at build time).
#  - AMF/QSV (AMD/Intel, libavcodec): link-imports the FFmpeg libs from FFMPEG_DIR (the BtbN gpl-shared
#    tree the client uses; includes the *_amf/*_qsv encoders) and bundles its DLLs into the installer.
# CI never launches the exe, so no GPU is needed here — this is build + Windows clippy coverage only.
