metabase-to-sigma

Migrate Metabase content to Sigma. Use when the user has Metabase questions, models, or dashboards and wants to recreate them in Sigma. Converts MBQL cards/models (+ database metadata) → Sigma data model and dashboards → Sigma workbooks, translating MBQL expressions/aggregations and flagging constructs with no clean Sigma analog. Discovery via the Metabase REST API (API key or session token) — works on open-source and Pro/EE alike.
