`sethiddenproperty`	Sets a Roblox property with reflection metadata. The first argument must be Instance object, the second argument must be a string property name, and the third argument must be present. The instance reference must be valid. If the property descriptor is missing from Roblox property metadata, the function returns nil. If the descriptor exists but does not resolve to a property entry, it raises “Not a property”. Bool values use luaL_checkboolean. Int and SystemAddress values use integer type checking, with SystemAddress writing RemoteId.PeerId. Float and Double values use number type checking. String, SharedString, and BinaryString values use string type checking before calling the setter. For other property types, the function temporarily calls setscriptable(instance, property, true), assigns instance[property] = value with normal Lua field assignment, then restores the original scriptable state with setscriptable(instance, property, isScriptable). On successful writes, the return value is a boolean equal to !IsScriptable() from before the write.
`setscriptable`	Luu scriptable override cho Roblox property trong scriptable override cache va tra ve previous scriptable state. Doi so dau tien phai la Instance object, doi so thu hai phai la string property name, va doi so thu ba phai la boolean. Neu da co cache entry cho cung instance reference va property name, cached scriptable value duoc thay the va cached value cu duoc tra ve.

Neu khong co descriptor, hoac field duoc resolve bi thieu hoac khong phai property entry, function tra ve nil. Khi tim thay property entry, function doc scriptable state, luu boolean duoc yeu cau cung property reference vao scriptable override cache, roi tra ve previous scriptable state value.
