### Summary This PR adds a dedicated documentation page describing the `Arrow ↔ Iceberg` type mapping for the `Java` implementation. While the mapping logic exists in `ArrowSchemaUtil`, it has not previously been documented in the user-facing documentation. The new page lives under `docs/docs/` and is grouped under a new `"Apache Arrow"` section within the `Integrations` category in `mkdocs.yml`. This creates a future‑proof home for Arrow-related documentation. A cross-link has also been added to `api.md` so users working with `Arrow` utilities can easily discover the mapping reference. ### Included - New page: docs/docs/arrow-type-mapping.md - New "Apache Arrow" subsection under Integrations in mkdocs.yml - Cross-link added to docs/docs/api.md - Iceberg → Arrow mapping table - Notes on decimals, timestamps, lists, maps, and UUIDs - Format-version notes for v3 types - Clarification that Java does not currently implement Arrow → Iceberg conversion - Implementation references ### Motivation Iceberg exposes Arrow schemas during vectorized reads, and users integrating with Arrow-based systems need a clear reference for how Iceberg types map to Arrow types. Creating a dedicated Apache Arrow section also provides a natural home for future Arrow-related documentation. ### Related Issues Fixes #15666 ### Testing Locally deployed and verified. <img width="1834" height="996" alt="Screen Shot 2026-03-20 at 1 40 47 AM" src="https://github.com/user-attachments/assets/a43fb938-ea3f-4d1f-a0ab-f9ac5f14243f"; /> <img width="1801" height="1002" alt="Screen Shot 2026-03-20 at 1 41 20 AM" src="https://github.com/user-attachments/assets/b46e9c5b-986b-42fb-998c-8e2a9bbda769"; /> -- This is an automated message from the Apache Git Service.
