  ### Description
  Fixes a fatal crash (concurrent map read/write) in `NewCompositedCompilerFromTemplate`.
  
  The `NewCompositedCompilerFromTemplate` function previously performed a shallow copy of `CompositionEnv`, sharing the `MapType` pointer across all compilers. Under high concurrency, this caused a race condition when `FindStructFieldType` (reader) and `AddField` (writer) accessed `MapType.Fields` simultaneously, leading to an APIServer panic.
