Runner Release 3.1.5

Container Runner:

• Version 3.1.5 introduces Windows support for container runner in open preview. For detailed setup instructions and configuration guidance, visit our Windows container runner documentation.
• Container runner now filters for pods specifically managed by each replica, rather than watching all task pods with the managed-by: circleci-container-agent label. This optimization reduces API load when running multiple container agent instances within the same cluster.
• Added support for running the primary container under a custom user ID (UID). You can now specify a valid UID using the docker.user key in your CircleCI configuration, which will be mapped to the task pod container user.
