docs(agent): close #41 — OpenFile portal float confirmed on hardware

Bernardo verified the GTK file-chooser (OpenFile) portal floats on real
hardware; the xdg-desktop-portal-gtk float/center rule already shipped in
hyprland.nix. Drop the "OpenFile not re-probed / optional residual"
caveats in HARDWARE-QUEUE and journal the V3 close. Bookkeeping only, no
code change.
