FFMPEG_DIR alone satisfies the linker, but the test binary needs the actual DLLs
on PATH at runtime. The daemon's own env (project-env.ps1, written by the
punktfunk-extras provisioning step) only takes effect on daemon *restart*, so a
freshly cloned/registered runner's first-ever job runs before that file has ever
been written, let alone picked up - confirmed live as STATUS_DLL_NOT_FOUND on the
new home-windows-runner-1's first real CI run. Setting PATH via GITHUB_PATH here
makes the workflow self-sufficient regardless of daemon restart timing.
