Pin dbatools.library to 2026.9.16 Azure compatibility preview

[potatoqualitee]

Type of Change

• Build system

Purpose

Pin dbatools CI and local development to the dbatools.library preview that contains the Azure dependency compatibility update from dataplat/dbatools.library#61.

Approach

Update the centralized .github/dbatools-library-version.json pin to 2026.9.16-preview-main-20260916195846. No workflow-specific versions are changed.

Commands to test

• Parsed .github/dbatools-library-version.json and asserted the exact requested version.
• Verified v2026.9.16-preview-main-20260916195846 is a published prerelease with an uploaded dbatools.library.zip asset.
• Ran git diff --check and independently reviewed the committed diff.

[potatoqualitee]

Blocking finding for this head: the pinned preview 2026.9.16-preview-main-20260916195846 was built from dbatools.library commit 56fd1f7, before Azure compatibility PR #61 merged as b1b63e0. The downloaded pinned ZIP still contains the older dependency stack (Azure.Core 1.51.1, Azure.Identity 1.18.0, MSAL 4.83.0, MSAL.Extensions 4.78.0, and System.ClientModel 1.10.0), so this pin does not deliver the stated Az.Accounts 5.5.1 compatibility fix despite the green import and SQL checks. Please change the pin to the published 2026.9.16-preview-main-20260916210307, which was built from b1b63e0, and rerun CI.
