ci(release): fail the PSGallery check on a query error instead of assuming not-published

[tablackburn]

Follow-up to the recovery-gap fix (#11). Now that Publish is gated only on the PSGallery check, Find-Module -ErrorAction SilentlyContinue returning $null for both a genuine miss and a transient query failure could trigger a blind publish. Fix: capture -ErrorVariable — publish only on a clean miss (genuine not-found records no error, verified), throw on a recorded error so the run is retryable. Surfaced by CodeRabbit/Copilot during the YTMP rollout. YAML parses; no manifest change.

📝 Walkthrough

Walkthrough

The workflow's PSGallery version check now captures errors from Find-Module and throws when a query fails, distinguishing transient network failures from genuine module absence while preserving success and not-found paths.

Changes

PSGallery Version Check Error Handling

Layer / File(s)	Summary
PSGallery existence check with error detection .github/workflows/PublishModuleToPowerShellGallery.yaml	The Find-Module query now uses -ErrorVariable to detect failures. If an error occurs, the step throws with the captured exception message instead of treating it as "not published." Module found and not-found cases preserve their existing exists=true and exists=false outputs.

Poem

A rabbit hops through PowerShell lanes,
Where errors once masked in the rains,
Now fail loud and clear when queries go wrong,
While true and false sing their publish song! 🐰✨

Pull request overview

Updates the release workflow’s PowerShell Gallery preflight check to distinguish a true “module version not found” from a transient PSGallery query failure, preventing accidental publishes when the lookup fails.

Changes:

• Captures Find-Module errors via -ErrorVariable while keeping the normal “not found” case silent.
• Throws (fails the job) when a PSGallery query error is recorded, making the run retryable instead of attempting a blind publish.
