fn resolve_lsp_profile_name(project_root: &Path) -> Option<String>Expand description
Resolve the active profile for LSP operations.
The language server has no CLI flags; it reads the project root’s
.mzprofile. Returns None if no profile is set — variable resolution,
suffix lookup, and cluster normalization all degrade gracefully (no
variables, no suffix), and SQL with :variables will surface
undefined-variable diagnostics as usual.
