Enhancement: Bumped latest stable build of python from 3.7 to 3.8, so the latter is now the default setting for pyright.
Enhancement: Added verbose logging for file system watchers.
Enhancement: Improved robustness of code that invokes the local python interpreter to query for paths. Thanks to Rami Chowdhury for the contribution.
