- Azure Blob URI builder (Build-BlobUri)
- S3 SigV4 signing helpers and AWS module bootstrap
- AD credential validation and replication permission pre-check
- Parallel execution helper (Get-FunctionDefinitionText)

Elysium.Common.ps1 for the first time. Update-KHDB.ps1 and
Prepare-KHDBStorage.ps1 removed their local duplicates.
Deleted legacy Settings.ps1 (superseded by ElysiumSettings.txt).
Removed stray placeholder comment in Elysium.ps1.
All versions bumped to unified v2.2.1.
