* It builds again!

* Turn on all the code again

* Tests compiling but not passing

* Stub work for value resolution

* Implement resolution minus enums and derived properties

* Implement property descriptor resolution

* Update referent snapshots

* Update unions test project

Using a place file instead of a model yields better
error messages in Roblox Studio.

* Add easy shortcut to testing with local rbx-dom

* Update rbx-dom

* Add enum resolution

* Update init.meta.json to use UnresolvedValue

* Expand value resolution support, add test

* Filter SharedString values from web API

* Add 'property' builder method to InstanceSnapshot

* Change InstanceSnapshot/InstanceBuilder boundary

* Fix remove_file crash

* rustfmt

* Update to latest rbx_dom_lua

* Update dependencies, including rbx_dom_weak

* Update to latest rbx-dom

* Update dependencies
