Function stamp_resolve_data 

pub(crate) fn stamp_resolve_data(items: &mut [CompletionItem], uri: &Url)

Index symbol kind → LSP symbol kind, aligned with the document-symbol outline’s choices (capability=INTERFACE, service/agent=CLASS, provider=OBJECT). The index does not distinguish type shapes, so every type maps to STRUCT. Map a completion::Completion to an LSP CompletionItem. Stash the document URI in each item’s data so completion_resolve can look the symbol up — a resolve request carries only the item, not a position.
