docs(agent): V2 the menu IA (#105/#111/#110) — content passes, file #131/#132

856a9d1 restructured the picker and shipped at "V0 menu-back; HM gen builds",
which §2.1 does not allow for a user-visible change. Rendered all eight
screens under the real HM session and viewed them.

IA verified: six-entry root; System → Connectivity/Devices/Recovery/
Preferences; Recovery lists each scope once; Preferences carries the migrated
update-checks/Bluetooth/Printing toggles; Control Center gone from the
dispatch (asserted, not eyeballed); no stderr on any screen. No code change.

Two findings, both filed rather than fixed:

#131 — the VM showed the long Recovery labels ellipsized. That specific
symptom is a guest artifact (they measure 462px/509px in Inter 11 against
~668px of room at 1920), but the same measurement says they DO truncate at
1366, where the picker is only 546px wide — cutting exactly the cost hint
#111 added them to carry. The Acer Aspire M5-481T is 1366x768 and in the QA
fleet. Shortening vs -mesg vs widening is a design call.

#132 — the guest draws icons at ~1/4 of ui.iconSize and clips a 6-row root
behind a scrollbar despite lines=8. Root predates #105, so this is the test
environment, not a regression — but it means menu screenshots are evidence
for content and never for geometry. Documented in docs/TESTING.md §5 so the
next agent doesn't chase it.

+### 131. Recovery cost labels truncate on 1366-wide panels
+
+#111 gave Recovery scope-first labels that carry the cost inline — "Desktop
+generation — themes & home config (instant, reversible)" (462px in Inter 11)
+and "System boot generation — older NixOS (reboot, then pick in boot menu)"
+(509px). The picker is `width: 40%`, so text room is ~668px at 1920 (fits)
+but only ~446px at 1366 — **both long labels ellipsize, and the cost hint is
+exactly the part that gets cut**. The Acer Aspire M5-481T (1366×768) is an
+active QA machine, so this is live, not theoretical. Options: shorten to
+"Desktop generation (instant)" and put cost in a rofi `-mesg` line, widen the
+picker for narrow screens, or let rofi wrap. Measured, not observed — the VM
+renders menu geometry unfaithfully (see #132); confirm on the Acer.
+
+### 132. VM cannot judge rofi menu geometry
+
+The guest renders the picker with icons at roughly a quarter of `ui.iconSize`
+(44 → ~10px) and rows short enough that a 6-row root clips its last entry
+behind a scrollbar, though `lines = 8` and `dynamic = true` should fit it.
+Root is unchanged since before #105, so this is the guest's font/icon
+environment, not a regression — but it means `theme-shot.nix`/`menu-shot`
+screenshots are trustworthy for **menu content** and not for spacing, icon
+size, or truncation. Either fix the guest (fontconfig + icon cache in the
+test node) or document the gap in docs/TESTING.md §5 so the next agent does
+not chase it — right now nothing warns them.
