[ENHANCEMENT] extend file event monitoring beyond active VSCode session

[d-biehl]

Currently, VSCode sends file events exclusively for actively opened files and folders. To enhance functionality, it is proposed that the capability to monitor file events for files and folders beyond the current VSCode session be implemented.

The preferred solution involves manual installation of the watchdog3 Python package (https://pypi.org/project/watchdog3/). It is recommended to verify the presence of this package. It's worth noting that due to the inclusion of binary files in the watchdog library, constructing a Universal Extension may not be feasible; consequently, native versions need to be developed.
