The BG3 fast install of 2026-10-23 downloaded 160 GB, was refused by the
installer, and the web job still ended on a full bar, "Done!" and Succeeded
while Steam restarted the download from 0%.
- A failed run's reason is read from the installer's own run log (its ERROR
lines). A waiting job prints "Failed: fast install of <game>: <reason>",
which fails the job; `install` no longer says "Done!" after it.
- Daemon-started failures stay on the Dashboard's Fast install card (and in
ctl status, `error`) until a new run starts or the game is installed.
- install_game writes Steam's "needs downloading" manifest before the
installer runs: it only finishes a manifest it finds, so fresh installs
were refused for want of one.
- Command building moved to _fast_install_cmd (250-line cap).
