Function compile_object 

fn compile_object(
    descriptor: ObjectDescriptor,
    object_key: String,
    fingerprint: String,
    profile: &str,
    variables: &BTreeMap<String, String>,
    profile_set: bool,
    file_entries: &BTreeMap<PathBuf, String>,
) -> ObjectCompileResult

Compile a single object and wrap the result for cache persistence.

Delegates to compile_object_uncached for the actual compilation, then serializes the result into a CompiledObjectArtifact and packages it with the object key and fingerprint into an ObjectStateRow ready to be upserted into the SQLite cache.
