Pull request overview

This PR changes the default behavior of "bolt run" to execute applications as a non-root user (UID/GID 34567) instead of root (UID/GID 0), with the --develop option available to restore previous root-based behavior for debugging purposes.

Key Changes:

• Introduced non-root default user credentials (UID/GID 34567) for improved security
• Modified runtime configuration template generation to support dynamic user namespace mappings based on options
• Enhanced device node permission handling to ensure non-root users can access required devices
