Python Integration

Python (sqlglot) is used for raw SQL input, duckplyr frames, and dbplyr pipelines that embed raw SQL. It is provisioned automatically; this helper checks availability

has_sqlglot()

Is the Python sqlglot dependency available?

Bundle Management

The React Flow bundle ships pre-built; this helper checks it exists

has_bundle()

Is the React Flow bundle available?
