Upgrade bux-lsp to 0.2.0 with a richer lightweight symbol index: func signatures, typed let/var/const, struct/enum/interface/type/module. Skip comments and strings while scanning. Hover shows markdown Bux code fences; definition resolves in-file and across workspace .bux files; documentSymbol provides outline. Fix responses writing to stdout (stdin was a broken pipe). didChange refreshes symbols; diagnostics still run via buxc on open/save.
