scripts(backup-notifications): unify push + email format across VDS/RUVDS/windows-host

3 host-pipelines (VDS bash, RUVDS+windows-host ps1) had drifted formats:
ntfy title `VDS backup OK $D` vs `RUVDS backup OK ($D)`, tags
`white_check_mark` vs `green_circle`, email subject `[VDS] backup OK` vs
`RUVDS backup -- SUCCESS`. Phone-side фильтрация и desktop reading
ломались за счёт inconsistency.

Unified to:
- ntfy push: title `<HOST> backup OK <date>`, body
  `<duration_human>, size=<>, snapshots=<>, dest=kreknin:<>`,
  tags `green_circle` (OK) / `red_circle` (FAILED).
- email: subject `[<HOST>] backup <STATUS> <date>` (STATUS=OK|FAILED),
  body — structured Date/Duration/Size/Snapshots/Source/Dest/Components/Log.
  Failure body extends with `Tail (last 40 lines)`.

Also imports VDS `run.sh` into repo as `scripts/vds-backup-rsync-kreknin/`
— closes drift из общего `scripts/<slug>/` pattern (RUVDS+windows-host
уже жили там; VDS жил только на /opt/stacks/backup/scripts/).

Deploy status:
- VDS: deployed via scp + sudo install, sha256=27b09ca272bb, smoke ntfy+email ✓
- RUVDS: deployed via scp + Move-Item, sha256=f3bb57a86af5, smoke ntfy+email ✓
- windows-host: deploy.ps1 + smoke-notify.ps1 готовы в scripts/, **pending
  elevated PS у user'а** (ACL=SYSTEM+Administrators, не пишется без UAC).

Spec + decisions + completed: .tasks/unify-backup-notifications.md.

 # Admin Task Board
-_Updated: 2026-05-24 (`books-ssh-audit-shared-vds` 🟢 closed — audit clean: 1 retained vitya key, 0 revoked, removed cosmetic dead root key, sshd hardening verified via `sshd -T`. Doc в `.wiki/concepts/books-ssh-access.md`. Pre-cutover acceptance для tenant-split Phase 3 ✅. Earlier today: `windows-host-fallback-backup-daily` 🟢 closed (daily 03:00 MSK rclone SFTP windows-host → kreknin live, 23 GB / 4868 sec smoke #1). Все 3 host'а (windows + RUVDS + VDS) backup'ятся на kreknin sequentially за одну ночь. Current scope: IIS migration в soak (kupimknigi + emspb flipped, tandemmebel excluded), infra-inventory ready, остальные books-* awaits tenant-split Phase 3-4 design Direction.)_
+_Updated: 2026-05-25 (`unify-backup-notifications` 🟡 paused — 3 scripts edited под единый push+email format; VDS+RUVDS deployed + smoke notify ✓; windows-host deploy pending elevated PS у user'а. VDS `run.sh` импортирован в repo как canonical source. Pre-existing: `books-ssh-audit-shared-vds` 🟢, `windows-host-fallback-backup-daily` 🟢, все 3 daily backups live на kreknin.)_

+## 🟡 [unify-backup-notifications] — единый формат push + email для всех 3 backup-pipelines (VDS / RUVDS / windows-host)
+
+**Status:** paused (pending windows-host elevated deploy)
+**Where I stopped:** 2026-05-25 — 3 scripts edited + parser-check ✓. **VDS + RUVDS deployed + smoke notify ✓** (ntfy_ok + email_ok с TEST-prefix). **windows-host pending elevated deploy** — `scripts/windows-host-fallback-backup-daily/deploy.ps1` готов, user запустит из elevated PS позже. Smoke на windows-host skipped по user-decision (доверяем parser-проверке).
+**Next action:**
+1. User: open elevated PowerShell, `cd C:\Users\vitya\projects\.admin`, `& .\scripts\windows-host-fallback-backup-daily\deploy.ps1`.
+2. (Optional) `& .\scripts\windows-host-fallback-backup-daily\smoke-notify.ps1` — отправит TEST ntfy + email, verify format.
+3. Verify первой ночью (2026-05-25 03:00 MSK windows-host → 04:30 RUVDS → 05:00 VDS) что push'и + email'ы пришли с единым форматом, нет regression.
+4. Закрыть task.
