v0.1.1 — fix Steam bootstrap + Walker refresh

Two issues found during first-run-machine test:

- Steam was installed but never auto-launched, so the first-run client
  update never happened — Gaming Mode failed to enter Big Picture
  cleanly. Now follows omarchy-install-gaming-steam's pattern: setsid
  gtk-launch steam &, disown, runs in parallel with the rest of the
  install.

- Walker didn't pick up the deckshift-settings.desktop entry until the
  next manual elephant restart. setup_settings_tui now calls
  omarchy-restart-walker after update-desktop-database, which restarts
  elephant.service + the walker autostart unit.
