[codex] Fix Windows workspace change path assertion

[TabishB]

Summary

• Normalize the workspace change CLI output before asserting the created change path.
• Keep the assertion focused on the displayed location while allowing Windows backslashes.
• Add an empty changeset because this is test-only and has no release impact.

Root cause

The previous fix removed the command failure, but this test still hard-coded a Unix-style path. On Windows PowerShell the CLI prints the workspace-relative path as changes\cross-repo-login/, so the main-branch Windows matrix failed even though the command succeeded.

Validation

• pnpm exec vitest run test/commands/artifact-workflow.test.ts -t "creates workspace-planning changes under the workspace root without touching linked repos"
• pnpm exec vitest run test/commands/artifact-workflow.test.ts
• pnpm exec changeset status --since=origin/main
• git diff --check

Summary by CodeRabbit

• Tests
  • Improved cross-platform test reliability to ensure consistent test behavior across different operating systems.

Walkthrough

This PR adds cross-platform path handling to the artifact workflow test by normalizing path separators before asserting on CLI output, and includes a changeset file documenting the fix.

Cross-Platform Path Normalization

Layer / File(s)	Summary
Path separator normalization for artifact workflow test test/commands/artifact-workflow.test.ts, .changeset/neat-cameras-press.md	The workspace-planning test now calls normalizePaths() on the CLI output before checking for the expected changes/cross-repo-login path segment. A changeset file documents this cross-platform fix.

Looks good. The normalizePaths() assertion is the right cross-platform fix, and checks are green.
