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.

+## 2026-07-10 — #41 hardware-confirmed: OpenFile portal floats (V3 close)
+- **Task:** BACKLOG #41 — final on-hardware confirmation (Bernardo reported PASS).
+- **Did:** #41 already out of NEXT + portal rule shipped
+  (`hyprland.nix` xdg-desktop-portal-gtk float/center). Bernardo verified the
+  GTK OpenFile file-picker floats on real hardware; dropped the "OpenFile not
+  re-probed / optional residual" caveats in HARDWARE-QUEUE — #41 fully closed.
+- **Verified:** **V3** (Bernardo, Latitude). No code change. Bookkeeping only;
+  QA-sweep guards run green this session: `nix flake check --no-build`,
+  option-docs/template-sot/theme-sync-validate builds, contrast 24×7.
+- **Pending:** none for #41. NEXT head is #76 (hibernation + zram, `[big]`).
+- **Next suggestion:** split #76 — take the low-risk **zram-default** slice
+  (V2-testable headlessly) before the boot-critical hibernate/resume work.
