 Known Issues / Follow-ups:
-- lua-language-server (lua_ls) from Mason failed to start due to missing shared library `libbfd-2.38-system.so`. Options:
-  - 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; validation done with other servers (jsonls, intelephense).
+- lua-language-server (lua_ls) from Mason failed to start due to missing shared library `libbfd-2.38-system.so`. **RESOLVED**: Installed lua-language-server via system package manager (pacman) instead of Mason. Removed `lua_ls` from Mason's ensure_installed list in `lua/plugins/mason-lspconfig.lua`.
 - 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.
