v1.2.0 — Modular agent runtime

v1.1.0 — API production-readiness pass

Polish boot UX + Thorox branding for video demo

- flake.nix: fix malformed packages output (was applying overlay incorrectly)
- Plymouth: logo now says "Thorox" instead of "AgentOS"
- Setup wizard: Thorox branding, WiFi hint (nmtui) for ISO users,
  gateway readiness poll before redirect instead of hard 3s timeout
- Sway kiosk: hide cursor after 3s inactivity, only show swaybar
  when Waybar is disabled, "Exit Thorox?" in swaynag
- iso.nix: remove duplicate kernel params (module handles them),
  updated comments for Thorox branding
- install.sh: update repo URL to bolivian-peru/agent-os,
  log prefix now [thorox]
