feat(nvim): add manual mode for LSP servers

Allow LSP servers to be enabled on-demand via a buffer-local command
instead of auto-starting on matching filetypes. The command name is
auto-derived from the server name (e.g. 'GolangciLint'). Switch
golangci-lint to manual mode as it's resource-heavy and not always needed.
