CLI: Handle Reprint retry-later exits without advancing the pull

[adamziel]

Keeps Studio on the interrupted pull step when Reprint returns exit code 3, instead of treating that step as complete.

Supports WordPress/reprint#779.

Proposed Changes

Exit 2 still resumes immediately, including with older Reprint versions. Exit 3 waits 15 seconds before retrying the same command, then 45 seconds before one final retry. The progress message explains the wait. Only exit 0 completes the step; other failures stop the pull and retain the captured error details.

For example, if pull-db returns 3, 3, then 0, Studio waits 15 seconds, resumes pull-db from its saved state, waits 45 seconds, and resumes it again. Only after the 0 does Studio move to the next step. A third 3 stops the pull. An exit 2 between these failures does not reset the retry limit.

The bundled Reprint stays at v0.10.4. This change does not require the new JSON fields, so it can land before a separate Reprint version bump. Both native PHP and Playground use the same retry behavior.

Testing Instructions

Pull a site with the bundled v0.10.4 and confirm it still completes. Then use a PHAR built from Reprint trunk against a disposable remote that returns HTTP 503 during pull-db. Confirm Studio shows the retry waits and stays on the database step. Restore the remote during a wait and confirm the pull resumes. Keep it unavailable through both retries and confirm Studio stops with the error details instead of proceeding.

Pre-merge Checklist

• Have you checked for TypeScript, React or other console errors? Type checking, changed-file lint, 73 related tests, and the CLI build passed. The full desktop pull above remains a manual check.
