YQL-20239: Exract pure_ast and move to sql/v1/ide

2026-06-11T12:56:57Z

It is a preparation for a hover LSP method implementation. Query parser and a narrowing visitor are required for the feature, so I extract the logic to a module `pure_ast` from a `complete`. Also modules `complete` and `pure_ast` are moved to `sql/v1/ide/completion` and `sql/v1/ide/pure_ast`. commit_hash:58bed5f2e39bf4779e28468fe7de1e0c4fb2c4c3
