URL: https://github.com/apache/iceberg-rust/pull/2029
## Summary
Add comprehensive user documentation for the DataFusion integration,
addressing issue #2027.
## Changes
- Add `website/src/datafusion.md` documentation page covering:
- Catalog-based access with `IcebergCatalogProvider`
- SQL operations: `CREATE TABLE`, `INSERT INTO`, `SELECT`
- Metadata tables (`$snapshots`, `$manifests`)
- External tables via `IcebergTableProviderFactory`
- Partitioned tables and write modes (fanout vs clustered)
- Query optimization (projection, filter, LIMIT pushdown)
- Configuration options and limitations
- Add `crates/examples/src/datafusion_integration.rs` working example with
annotated code sections for documentation includes
- Update `website/src/SUMMARY.md` to include new documentation page
- Add required dependencies to `crates/examples/Cargo.toml`
## Notes
