Module tree 

Declarative completion-tree builders derived from command and config metadata. Declarative builders for the completion engine’s immutable tree model.

Public API shape:

• describe command surfaces with CommandSpec
• lower them into a cached crate::completion::CompletionTree with CompletionTreeBuilder
• keep the resulting tree as plain data so the engine and embedders can reuse it without retaining builder state

Structs
