* Mostly mechanical port bits * Almost there * 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 * Update rbx-dom, fixing more bugs * Remove experimental warning on binary place builds * Remove unused imports

-- The aim of this API is to facilitate looking up a property once, then reading
|
|
-- from it or writing to it multiple times. It's also useful when a consumer
|
|
-- wants to check additional constraints on the property before trying to use
|
|
-- it, like scriptability.
