Add rewriteBqLogsSqlToClickhouse: parses the user's BigQuery logs query with
the polyglot SDK, rewrites it onto the OTEL logs schema on the AST (FROM logs +
source filter, drop unnest joins, nested fields -> log_attributes[...] with
numeric casts), and regenerates ClickHouse SQL. The banner's button now runs
this directly on the editor and only falls back to the AI Assistant when it
can't. Lazy-loaded so the WASM stays out of the main bundle.
