Module precompile 

Compiling WASM artifacts ahead of their first launch.

mur install and mur precompile hand each payload to Precompiler::precompile, which stores its compiled form through the same [CompiledForms] handle and the same stage_root_component that stage_session uses, on an engine from the same build_engine. A form written here therefore has the name, mode, sidecar and stamp a launch would have given it, and launch cannot tell the two apart. This module reads and writes no file itself.

The key is the sha256 of the payload bytes in hand, recomputed here, so a form is only ever compiled from the root wasm of the payload it is named after, as the key contract in compiled_forms requires.
