fix(theme): #79 review fixes — wrap-around schedule + HH:MM guard

Two low-severity edge bugs from a fresh-eyes review of the session batch:

- cmd_auto: an inverted schedule (sunrise > sunset, i.e. a day window that
  crosses midnight) stayed perpetually on the day theme — the old
  `not between` shortcut is an empty interval when sunrise > sunset.
  Replaced with a real wrap-around: daytime = mins >= sunrise or
  mins < sunset, so both directions switch. Normal sunrise < sunset path
  is unchanged (checks.auto-theme still holds).
- rofi autotheme HH:MM validator: `[0-2][0-9]` accepted 24:00–29:59.
  Tightened the case pattern to `[01][0-9]:[0-5][0-9]|2[0-3]:[0-5][0-9]`
  so out-of-range hours are rejected (they'd otherwise skew the boundary).

(Two other review findings dismissed: papirus DOES ship breeze/breeze-dark
so that iconPacks prefix is correct; the doctor RAM-unknown row is cosmetic
since /proc/meminfo is always readable.)

Verification: py_compile; boundary truth-table (normal + wrap-around);
HH:MM case table (23:00/19:59/20:00 accept, 24/25/30:00 reject); auto
--which normal-case unchanged; menu bash -n; flake check green.

+## 2026-07-11 — Code-review fixes (parallel review of the session batch)
+- **Task:** Bernardo asked for parallel work; spawned a fresh-eyes opus
+  review of `2055842..HEAD` (static). It found the batch sound — 2 real LOW
+  edge bugs, 1 false positive, 1 cosmetic.
+- **Did:** (1) `cmd_auto` — inverted sunrise/sunset (sunrise > sunset) went
+  perpetually day; replaced the `not between` shortcut with a real
+  wrap-around `mins >= sunrise or mins < sunset`, so a cross-midnight day
+  window switches both ways. (2) `rofi.nix` autotheme HH:MM guard tightened
+  `[0-2][0-9]` → `[01][0-9]|2[0-3]` so 24–29 are rejected. Dismissed the
+  `breeze` finding (papirus DOES ship breeze/breeze-dark — verified) and the
+  cosmetic doctor-RAM one.
+- **Verified:** py_compile; boundary truth-table (normal + wrap-around);
+  HH:MM case table (23:00/19:59/20:00 accept, 24/25/30:00 reject); `auto
+  --which` normal-case unchanged; menu bash -n; flake check green. Normal
+  case unchanged so `checks.auto-theme` still holds.
+- **Pending:** hibernate-swapfile VM test still running (uncommitted flake.nix).
+- **Next suggestion:** land hibernate-swapfile once its VM test returns.

 ## 2026-07-10 — #79 V2: checks.auto-theme (simulated sunset) — was mis-framed V3
 - **Task:** Bernardo challenged the "V3 real-session" framing — a simulated
   sunset IS VM-testable. He's right; I'd conflated "needs a real desktop"
