feat(doctor): #77 hibernate/sleep section (VISION § C)

nomarchy-doctor gains a read-only hibernate/sleep section (the highest-ROI
Day-2 gap, a natural #76 follow-on): resume device on the kernel cmdline
(+ resume_offset for a swapfile), disk swap >= RAM, zram active, and any
suspend/hibernate error in the previous boot's kernel log. Self-gates
(skip on swap=0) and emits only ok/warn/skip, so it never fails the sheet.
Adds `hibernate` to the checks.doctor probe list so the row is asserted.

Fixes a set -euo pipefail hazard the first VM run caught (exit 1, no
verdict): a no-match grep inside $(...) and a `cond && action` both abort
under set -e — now guarded with || true / || echo 0 / if. Recorded in
MEMORY as a reusable gotcha for writeShellScriptBin scripts.

Verification: V2 PASS — checks.doctor VM test green (fresh build, exit 0;
asserts the hibernate row renders, healthy run stays 0). V1 — ran on real
LUKS+@swap hardware: all three ok rows render (resume set, swap 34G >= RAM,
zram 16G) and the sheet reaches its verdict. V0 bash -n + flake check.

+## 2026-07-10 — #77 doctor hibernate/sleep section (V2 PASS)
+- **Task:** BACKLOG #77 (promoted from PROPOSED by Bernardo) — read-only
+  hibernate section in nomarchy-doctor (`VISION § C`, #76 follow-on).
+- **Did:** Added a hibernate/sleep row group to `nomarchy-doctor.sh`: resume
+  device on cmdline (+ `resume_offset` for a swapfile), disk swap ≥ RAM,
+  zram active, previous-boot suspend/hibernate error. Self-gates (`skip` on
+  swap=0); only ok/warn/skip → never fails the sheet. Added `hibernate` to
+  the `checks.doctor` probe list.
+- **Verified:** **V2 PASS** — `checks.doctor` VM test green (fresh build,
+  exit 0; asserts the hibernate row renders + healthy run still 0). **V1** —
+  ran on this box's real LUKS+@swap layout: all three `ok` rows render
+  (resume set, swap 34G ≥ RAM, zram 16G) and the sheet reaches its verdict.
+  **V0** bash -n + flake check.
+- **Gotcha (fixed + MEMORY):** the doctor runs `set -euo pipefail`; my first
+  cut aborted before the verdict because a no-match `grep` inside `$(…)` and
+  a `cond && action` both trip set -e. Fixed with `|| true` / `|| echo 0` and
+  an `if`. First VM run caught it (exit 1, no verdict) — the test earned its keep.
+- **Pending:** none — fully agent-verifiable (read-only checks, no V3).
+- **Next suggestion:** NEXT head is #76 `[blocked:hw]`; remaining PROPOSED
+  (Omarchy doc §F, auto time-of-day theme §D) await triage.
