docs(agent): clean QA sweep + VISION-gap pass (3 PROPOSED)

QA/drift sweep: deterministic checks + bash -n/py_compile all pass
(the 4 "needs-args" scripts pass via their flake derivations); drift
recon found none (dead code, stale refs, TODOs, changed-area
contradictions, counts all clean — 24 presets/previews consistent);
eval sweep green. No fixes needed.

VISION-gap pass: verified candidates against the tree first, which
killed two false gaps (nomarchy-rebuild/home already tail logs + point
at doctor on failure = §A; nvd diff = §B; Firmware menu already exists).
Filed three verified-open PROPOSED items: doctor hibernate/sleep section
(§C, natural #76 follow-on), Omarchy migrant one-pager (§F), auto
time-of-day theme pair (§D, big). Await human triage.

Verification: V0 (agent-notes/docs only); flake check --no-build green.

 ### Product / day-2
 
+- **Doctor: hibernate/sleep section** (`VISION § C`) — the doctor covers
+  units/disk/flake/network/audio/GPU/fingerprint/fwupd/charge but has **no**
+  hibernate check, even though #76 just made hibernation a default. Add a
+  read-only section: `resume=`+`resume_offset` present on `/proc/cmdline`
+  (or acknowledge the `swap=0` opt-out), a disk swap ≥ RAM present, zram
+  active at its priority, and no failed suspend/resume in the recent journal.
+  Self-gating (skip when swap=0). Why: "trust > new power UI." Cost: ~1
+  iteration, V2-guardable — the highest-ROI Day-2 gap found + a natural #76
+  follow-on. (Verified 2026-07-10: no resume/swap/hibernate lines in
+  `nomarchy-doctor.sh`.)

 ### Theme polish
 
+- **Auto time-of-day theme pair** (`VISION § D`) `[big]` — no scheduled
+  light/dark theme switch exists today (only night-light gamma via hyprsunset
+  + wallpaper `bg auto`). Let a user pair two shipped themes (e.g.
+  summer-day ↔ summer-night) and switch on a schedule/sunset through the
+  **existing** engine — a systemd timer running `nomarchy-theme-sync apply
+  <slug>` — staying one theme engine (GOALS: no second pipeline). Split
+  before starting: (a) state schema for the pair + schedule, (b) the timer/
+  hook, (c) menu surface. Cost: multi-slice; verify each `apply` still bakes
+  one clean generation. (Verified 2026-07-10: no time-of-day/auto-theme
+  scheduler in the tree.)

+- **Omarchy migrant one-pager** (`VISION § F`) — no Omarchy→Nomarchy guide
+  exists (MIGRATION.md is NixOS→Nomarchy; RECOVERY is recovery). Omarchy is
+  the closest sibling and the likeliest source of new users. A short `docs/`
+  page mapping the deltas: keybindings, the theme system (`nomarchy-theme-sync`
+  vs Omarchy's), the install path (ISO vs Arch script), and what feels the
+  same (Hyprland/Waybar). Docs-only, low-risk, adoption-facing. Cost: small.
+  (Verified 2026-07-10: no "omarchy" mentions in docs beyond VISION's idea.)
