PR Summary

Add a native test operation to the DSC Repository resource. Compare absolute local paths and file URIs in the same canonical form so a second dsc config set skips a repository that already matches. Report the differing properties when the URI or another configured property actually changes.

Fixes #2055.

PR Context

Registering a path like C:\Repo stores a URI like file:///C:/Repo. DSC's synthetic test compares the strings and treats the repository as out of state. The native test returns the actual state and the properties that differ. Exported configurations omit the read-only DSC test status.

The new repository lifecycle test failed on upstream and passed with the patch. The Release build passed, followed by 12 Pester repository and schema tests on DSC 3.3.0 and 13 CLI checks each on DSC 3.2.0 and 3.3.0. The CLI checks confirmed that a second apply skips the repository-store write and that a different path still updates the registration. Validation ran on PowerShell 7.6.5 for Windows. PSScriptAnalyzer reported no new findings.

Codex assisted with the implementation and validation.

🟡 Changes recommended

Repository drift tests omit independent changes to trusted, priority, and repositoryType, leaving unverified whether DSC detects those differences and converges rather than silently skipping updates.

What changed in this PR

Adds native DSC testing for the Repository resource to address #2055, allowing equivalent local paths and file URIs to be recognized as the same repository.

Changes:

• Compare configured properties with actual repository state and report differences.
• Add read-only test status while excluding it from exports.
• Add regression coverage for repeated local-path applies and URI changes.
