Function lsp_checks 

pub(crate) fn lsp_checks(
    snapshot: &PluginsInventorySnapshot,
    path_var: Option<&str>,
) -> Vec<LspServerCheck>

One check per declared LSP server of an INSTALLED plugin, in scan order. An uninstalled plugin’s declared servers are not probed: the page’s LSP pane draws installed rows (the plugin is the install unit), so a check for a plugin that is not here is weight nothing draws.
