Errors shown on `cargo miden build`, but they don't break the build

```
[ERROR miden_core::mast::serialization] UntrustedMastForest expected HASHLESS input; supplied artifact includes wire node hashes, and validation will recompute them and require them to match
[ERROR miden_core::mast::serialization] UntrustedMastForest expected STRIPPED input; supplied artifact includes DebugInfo and other optional payloads over the wire
[ERROR miden_core::mast::serialization] UntrustedMastForest expected HASHLESS input; supplied artifact includes wire node hashes, and validation will recompute them and require them to match
[ERROR miden_core::mast::serialization] UntrustedMastForest expected STRIPPED input; supplied artifact includes DebugInfo and other optional payloads over the wire
```

The error originates in `miden_core::mast::serialization`. Look at the `cargo miden build` command flow and the `UntrustedMastForest` validation logic. Examine the serialization format and what 'HASHLESS' and 'STRIPPED' inputs entail. Check if a recent PR (#1239) addressed this and verify the current state by running the build command and inspecting the logs.
