v1.3.1

v1.3.1 — 2026-08-17

• Fixed: AC-3 Surround install/revert now works correctly when the
  toolkit is run via sudo. PipeWire and WirePlumber commands are
  executed in a separate user-session script (ac3-user-setup.sh) as
  the real user, fixing card detection failures and hangs that occurred
  when pactl/systemctl --user were called as root.
• Fixed: WirePlumber config corrected to use api.acp.disable-pro-audio
  instead of api.alsa.use-acp, matching Valve's working valve-fremont
  hardware profile. The previous setting prevented the hdmi-ac3.conf
  profile set from loading, leaving only generic on/off profiles.
• New: AC-3 Surround status now shown in "Verify My Setup" (option V)
  with a dedicated Audio section showing whether AC-3 is installed and
  whether the profile is currently active.
• Changed: Toolkit logs (trace, run, error, diagnostic) now saved in
  <toolkit-dir>/logs/ instead of ~/.bc250-toolkit/logs/. Error logs
  are still copied to the Desktop on failure.
