nixpkgs plugin.dependencies breaking lazy-loaded plugins

[horriblename]

⚠️ Please verify that this bug has NOT been reported before.

• I checked all existing issues and didn't find a similar issue

Description

currently startPlugins and optPlugins .dependencies are installed automatically (by mnw).

This causes duplicate plugins installed, and may break a lazy-loaded plugin.

Example: Telescope

with our telescope option enabled, and adding a telescope extension like telescope-undo from nixpkgs, we end up with nixpkgs' telescope in start/ and our telescope in opt/

The one in start/ will load telescope on startup

When a keybind is triggered, lz.n will remove the existing :Telescope command and run telescope.setup

at this point the setup doesn't re-add :Telescope as telescope just assumes it's already loaded

so we end up with a missing :Telescope command

👟 Reproduction steps

add a telescope extension from nixpkgs

👀 Expected behavior

doesn't mess with lazy-loaded plugin

😓 Actual Behavior

does
