If possible, configuring for your locally running framework or a schema registry client to handle schema updates and output to a `schema.graphql` or `introspection.json` will always provide a better experience. many graphql frameworks have this built in! Otherwise, we must use this new lazy polling approach if you provide a url schema (this includes both introspection URLs and remote file URLs, and the combination of these).

 Fixes several issues with Type System (SDL) completion across the ecosystem:
 
-- restores completion for object and input type fields when the schema context is not parseable
+- restores completion for object and input type fields when the document context is not detectable or parseable
 - correct top-level completions for either of the unknown, type system or executable definitions. this leads to mixed top level completions when the document is unparseable, but now you are not seemingly restricted to only executable top level definitions
 - `.graphqls` ad-hoc standard functionality remains, but is not required, as it is not part of the official spec, and the spec also allows mixed mode documents in theory, and this concept is required when the type is unknown
