* fix: avoid Windows crash after network requests
* fix: destroy dispatchers before Windows error exits
* test: cover destroyDispatchers and document its shutdown contract
Add a JSDoc to destroyDispatchers() explaining it is for process shutdown,
a unit test verifying it destroys the global and cached dispatchers, and bump
@pnpm/network.fetch to minor for the new public export.
* fix(network.fetch): destroy the active global dispatcher on shutdown
Include getGlobalDispatcher() so destroyDispatchers() also closes the
currently-active dispatcher if it was replaced via setGlobalDispatcher().
