Note

Low Risk
Single constant bump with no logic changes; only shifts the declared minimum Platform version for compatibility resolution.

Overview
Raises the minimum supported Loft Platform version from v4.10.3 to v4.11.0 in pkg/platform/version.go.

MinimumVersion is parsed from that constant and drives LatestCompatibleVersion (GitHub release selection and fallbacks) and related platform compatibility checks, so vCluster will now treat Platform 4.11.0+ as the floor.
