Symlink saves, rank prefixes by Steam app type, ntsync safeguards

- Replace copy-in/copy-out save deployment with a direct symlink from the
  prefix's __MO_Saves to the profile's saves/. Writes land in the profile
  immediately; afterRun reverts the symlink + prefix INI so a vanilla
  launch outside MO2 uses the default Saves dir.
- Parse Steam's binary appinfo.vdf (v41) via a new Rust FFI crate backed
  by steam-vdf-parser. Rank detected games by common.type so real Games
  beat Tools/Editors when multiple prefixes share a My Games folder name
  (fixes Creation Kit shadowing Skyrim SE). Top-ranked candidate
  overwrites stale symlinks from earlier runs.
- Switch bundled Steam Linux Runtime downloader from sniper (steamrt3)
  to steamrt4 so Proton 11+ works out of the box. steamrt4 omits xrandr
  so we inject it from the Debian x11-xserver-utils .deb into a
  dedicated dir and prepend it to PATH via `env PATH=...` inside the
  pressure-vessel container (PATH env doesn't propagate).
- Auto-kill stale wineboot/wineserver/pv-adverb processes still bound
  to the prefix before starting a new wineboot -u; match by
  /proc/<pid>/environ WINEPREFIX / STEAM_COMPAT_DATA_PATH since Wine
  cmdlines are Windows-style. Same sweep runs in destroyPrefix so a
  delete actually frees file handles.
- Blacklist Proton 11 (Steam-bundled) — its current Wine tree deadlocks
  during wineboot -u on modern kernels via ntsync / futex_wait_multiple
  races. Use "waitforexitandrun" (not "run") for prefix init so
  use_sessions=1 Protons don't fork into a persistent session manager.
- Drop WINEDEBUG=-all during prefix init so wineboot progress is
  visible. Suppress focus-stealing by setting WA_ShowWithoutActivating
  on the PrefixSetupDialog and SLR download progress dialogs.
