Pull request overview

This PR improves diagnostics in the WASM corerun host when loading Webcil/R2R modules fails because __stack_pointer is unavailable.

Changes:

  • Adds an explicit __stack_pointer availability check before WebAssembly instantiation.
  • Logs instantiation failures with the wasm path and error message.
