docs(agents): point PS→Python map at scripts/archived/

The shim mapping table now notes the .ps1 live in scripts/archived/
(frozen, lint-exempt, no live caller) and gains the Phase C host tools
(bench/smoke/validate host/creds set). Fix the "stays in PowerShell"
list: drop Test-CapacityBurnIn (archived) and the non-existent
Measure-CIBenchmark; keep retention/backup/template/e2e/Windows-side.
