Pull request overview
This PR optimizes the official build pipeline by enabling parallel execution of the localization and build stages, reducing overall build time by approximately 9 minutes. Previously, the build stage implicitly depended on the localization stage to complete first. By explicitly setting dependsOn: [] on the build stage, both stages can now run concurrently. The post-build stage will still wait for the build stage to complete (via the default validateDependsOn: [build] parameter in the post-build template), ensuring the correct sequencing of critical build artifacts.
Key Changes
- Added explicit empty dependency to the build stage to enable parallel execution with localization
- Localization stage continues to run independently and can complete at any time
- Post-build stage correctly waits for build stage but not localization

This should reduce our official build time by ~9 minutes by moving the Localization step off the critical path.
Before:
