[windows] constraints on max length of filesystem paths

[DerekNonGeneric]

Windows has a maximum length of 260 characters (by default), but can be increased by overriding environment variables (i think). I learned about this when installing Python 3 on Windows, which allows you to increase this size. We cannot really make these kinds of OS-level configuration changes w/ a package of this nature.

We should ensure that this limit is not exceeded by this package — I am not sure what happens if it does exceed this length, but probably nothing desirable.

const MAX_PATH_LENGTH:number = 260;

I don't yet have any references to link to for this…

Something from Windows Server Docs would be great (preferably Windows Server 2022).
