- Add plans/idea-3-powershell-removal.md: Phase C goal is to eliminate
the pwsh dependency from the Linux host by porting the remaining PS
scripts (bench run, validate host, smoke run) to Python sub-commands.
- Update idea-3-esxi-support.md header: Fase C → Fase D.
- Update ideas-overview.md: new four-phase table (A/B/C/D) with
prerequisiti and criteri for Phase C.
- Rename all "Hook futuri Fase C" (ESXi) → "Hook futuri Fase D" in
implementation-plan-A-B.md; add Phase C/D entries to summary and
references section.
- Update PhaseB-user-checklist.md end note and CLAUDE.md to point
Phase C → pwsh removal, Phase D → ESXi.
