Removes strict-boolean-expressions because its too noisy

Avoids unneeded `void`s to know if return value is intentionally discarded
Uses `type` imports when possible (avoids unneeded bundling)

This enables basic multi-select support, but commands have not been audited for proper support and may fail completely or corrupt data (try it at your own risk)

Commands run with multi-select will sequentially execute the command for each selected item (assuming each item is of the same type at the active item, e.g. the item the context menu was shown for), unless they are specifically multi-select aware.

Currently only dropping stashes is now multi-select aware.
