docs(agent): file #125 ISO still named nixos, #126 display res invert

Bernardo: live/install ISO artifact is nixos-live-….iso (image.baseName);
live VM Display picker appeared to invert higher/lower modes — investigate
sort/apply vs QEMU scaling before fixing.

+## 2026-07-15 — File #125 ISO name + #126 display resolution invert (no code)
+- **Task:** Bernardo: (1) installer ISO still named nixos; (2) live VM
+  Display picker — higher modes made the screen look lower-res.
+- **Did:** NOW **#125** — artifact is `nixos-live-….iso` because
+  `image.baseName` is still the nixpkgs default; volumeID already
+  NOMARCHY_LIVE. **#126** — rofi display mode list/apply path; separate
+  sort bug vs QEMU scaling before coding.
+- **Verified:** V0 (docs/agent only); confirmed `result/iso/nixos-live-…iso`
+  on tree.
+- **Pending:** implement when picked.
+- **Next suggestion:** still #123 (HM pre-activate), or #125 if a one-liner.

 ## 2026-07-15 — #95 complete: Kitty is the only terminal (this commit)
 - **Task:** Bernardo: make kitty default and only option — drop dual-terminal
   complexity (Ghostty failed on Acer OpenGL 4.2; fallback was more code).
