Subject: [PATCH] =?UTF-8?q?ci:=20retry=20+=20explicit=20Node=2020=20versio?=

Symptom (run #1826 fail на u4-runner):
  Bootstrap step молча установил Node 12 (Ubuntu default) вместо Node 20
  из NodeSource → actions/checkout@v4 не парсится (ES2022 static blocks).

Cause:
  curl ... setup_20.x на slow network (u4 через VPN) timeout/fail silently,
  apt install fallback на default ubuntu nodejs (Node 12). Без error.

Fix:
  - curl --retry 3 --retry-delay 5 --connect-timeout 30
  - retry-loop на NodeSource setup (3 попытки)
  - явная verification major version >= 18 после install, fail с exit 1
    если установился Node < 18

Применяется к обоим jobs (cmake-build и filter-build).

Связано: PR #4 (v0.2), run #1826 fail.
