   - Install lua-language-server via system package manager compatible with your distro.
   - Provide the required `libbfd` or adjust symlink to match expected soname.
   - Skip lua_ls for now; neoconf validation can be done with other servers (e.g., jsonls) and PHP (intelephense).
+- LSP root detection: In some cases, the parent repository is picked as the root (e.g., when a workspace lives inside another repo). Workaround: create an empty `.git` directory (or a marker like `.nvimroot`) in the intended workspace root to pin the project root for LSPs.
