Sync codex-desktop-linux with v0.4.1 release content

[github-actions]

v0.4.1 released. Update codex-desktop-linux to pin/ship this version and mirror the relevant changes.

v0.4.1 changelog

Fixed

• Targeted get_app_state screenshots now crop to the resolved target window,
  and refuse the full-desktop fallback when a target was requested but window
  bounds cannot be resolved or the window is entirely off-screen. (fix: correct Hyprland targeted screenshots #48)
• Hyprland window bounds are normalized against each window's monitor origin
  and fractional scale so portal screenshot coordinates align on
  multi-monitor and scaled (e.g. 1.8x/2.0x) setups. (fix: correct Hyprland targeted screenshots #48)
• Wayland sessions are recognized via WAYLAND_DISPLAY when
  XDG_SESSION_TYPE is unavailable, so the portal input fallback engages in
  environments that don't export the session type. (fix: correct Hyprland targeted screenshots #48)
• Window focus verification now allows up to one second for compositor
  workspace/focus transitions before reporting activation failure. (fix: correct Hyprland targeted screenshots #48)

Synced: avifenesh/codex-desktop-linux#6 merged, porting v0.3.1..v0.4.1 into the embedded copy (X11/EWMH backend, Hyprland 0.55 Lua focus dispatcher, MCP schema unsigned-format sanitization, targeted-screenshot crop + monitor-origin/scale rebase) with Codex naming re-applied. Embedded crate is now 0.4.1-linux-alpha1, matching the upstream enumeration.
