fix(lsp): stop dropping LSP plugins on a cold clone

This file required configs.lspconfig at spec-import time, which pulls in
nvchad.configs.lspconfig. On a fresh clone NvChad is not installed yet,
so the import threw and lazy skipped every spec below it — rustaceanvim,
typescript-tools, actions-preview, nui and lsp-endhints were all missing
until the second launch. Verified against a wiped profile.
