Sign-in skips org picker with one org; Azure DevOps reviews more reliable

CLI v0.5.4

v0.5.4 fixes common sign-in, review, and update edge cases.

• Browser sign-in now skips the organization picker when only one organization is available.
• Reviews resolve Azure DevOps repositories and unusual base branches more reliably, and ignore stale events from previous reviews.
• Piped output no longer reports expected broken-pipe closures as CLI errors.
• Installs and updates pick up new releases more consistently.
