Removed provisional support for [PEP 746]( https://discuss.python.org/t/pep-746-typedmetadata-for-type-checking-of-pep-593-annotated/53834 ) because the PEP has been modified, and there is disagreement about the best approach.

Enhanced isinstance narrowing logic to retain type arguments in cases where the filter type (the second argument) is a child of the un-narrowed type and the child has a type parameter that is used multiple times in its base class (e.g. Child[T](Parent[T, T])). This addresses #9141 . ( #9144 )

Added code to propagate information about certain typing module imports from an implicitly-imported module (e.g. builtins or __builtins__.pyi) so Final and ClassVar can be treated as special forms by the binder. This fixes the use of these typing symbols in notebooks within pylance, which leverages implicitly-imported modules to "chain together" notebook cells. This addresses #6455 .

Counting files seen ( #9087 )
...
Adds a counter for number of files seen. Only shows "too many files" error message if bigger than a given number (hardcoded to 50 same as number of seconds is hardcoded to 10).
This avoids throwing the error suggesting opening a subfolder when the long operation time for directory reading is actually due to the number of files being read (as opposed to very large, very few files).
