Description

Adds a PR-only Build test VSIX job to the existing Code QA workflow. The job builds the required workspace packages, packages Zoo Code, and uploads the resulting VSIX as a seven-day GitHub Actions artifact named for the pull request.

This gives contributors and reviewers an installable build for testing fixes before merge. The job keeps read-only repository permissions, disables persisted checkout credentials, uses no secrets, and does not create GitHub Releases or publish to either extension marketplace.

Test Procedure

1. Confirm the Build test VSIX check succeeds on this pull request.
2. Open the completed workflow run and download zoo-code-vsix-pr-<PR number> from its Artifacts section.
3. Extract the artifact and install the VSIX with VS Code's Extensions: Install from VSIX... command.

Locally verified with the exact workspace build and package commands; bin/zoo-code-3.78.0.vsix was produced. The full pnpm test suite passed with 7,538 tests, and the commit and push hooks also passed lint and type checking.

Additional Notes

GitHub requires signed-in repository read access to download workflow artifacts. External or first-time contributor workflows may also wait for maintainer approval according to repository or organization policy; the workflow intentionally does not use pull_request_target to bypass that safety control. A recent fork PR successfully uploaded an artifact through this same Code QA workflow and pinned upload action.
