Release v2.2.1

[2.2.1] - 2026-07-18

Documentation

• README.md: corrected the Pester test count (650 -> 678) and the PowerShell minimum (7.0, matching #Requires and the module manifest; 7.4+ recommended); PowerShell Gallery badges and install instructions; a note that all ./scripts/... examples map one-to-one to the exported module commands; mermaid architecture diagram in place of the ASCII flow; compliance-scan section now lists the companion CISAzureFoundationsBenchmark module with a benchmark-version clarification (ADE templates authored against CIS v5.0.0, the companion audits v6.0.0 — pick one scanner for both runs)
• docs/usage.md: cost table had drifted from the README (minimal ~$80-120 vs ~$15-30) — replaced with a pointer to the README's cost guidance as the single source of truth; hardened example now uses the canonical -Profile hardened -Mode hardened pairing; prerequisites aligned (Azure CLI 2.60+, PowerShell 7.0+)
• Documentation-only patch: refreshes the README bundled in the Gallery package; no script or template changes
