docs(runbook): record Windows host pre-migration baseline

Phase A benchmark data (2026-05-17): VM lifecycle avg 60.6s boot,
smoke job avg 27s Win / 49s Linux, 100% success rate (12/12 burn-in).
B7 reference thresholds: Win ≤32s, Linux ≤59s.

+## Windows host baseline
+
+**Data**: 2026-05-17 (Phase A closure — commit `36913ab6`)
+
+**Hardware**: Intel i9-10900X, 64 GB RAM, NVMe SSD
+
+**Versioni**:
+- `ci_orchestrator`: v2.0.0-phaseA (SHA `b4ca7f3`), Python 3.13.3
+- `act_runner`: v1.0.2
+
+**Benchmark infra — VM lifecycle** (`Measure-CIBenchmark.ps1`, 4 iter, template Windows):

+
+> Fase IP (20–85 s) = costo dominante e variabile (detect IP via VMware Tools). Normale, non bloccante.
+
+**Tempo medio per job** (smoke `self-test.yml`, Gitea Actions, Passo 6 Phase A):
+
+| Template       | Transport             | Wall time |
+| -------------- | --------------------- | --------- |
+| WinBuild2025   | in-guest git clone    | 26 s      |

+| **media Linux**|                       | **49 s**  |
+
+**Success rate**: 100 % — burn-in 12/12 (3 round × 4 job concorrenti, Passo 7 Phase A).
+
+> Questi valori sono il baseline di riferimento per il criterio B7 ("tempo medio entro ±20% baseline Windows"). Margini: Win ≤ 32 s, Linux ≤ 59 s.
