## Which issue does this PR close? N/A ## Rationale for this change The `docs/source/about/gluten_comparison.md` page was based on Comet 0.9.0 and Gluten 1.4.0 and did not cover several areas that have become material differentiators since then: ANSI mode (which Spark 4.0 enables by default), Spark 4.x version coverage, and Apache Iceberg integration. ## What changes are included in this PR? - Updated the version reference to Comet 0.14.1 and Gluten 1.6.0. - Added a "Spark Version Support" section listing the Spark releases each project targets. - Added an "ANSI Mode" section noting that Comet implements ANSI semantics for supported expressions while the Gluten Velox backend documents that ANSI mode causes fallback to vanilla Spark. - Added a "Table Format Support" section describing Comet's native iceberg-rust scan (spec v1/v2, schema evolution, time travel, MoR deletes, REST catalog) and acknowledging Gluten's broader native coverage of Delta Lake, Hudi, and Paimon. - Refreshed the Compatibility section with concrete pointers to known Gluten Velox limitations (case sensitivity, RE2 regex, NaN, timestamp encodings). - Rewrote the Summary to plainly state where each project leads today. ## How are these changes tested? Documentation only. Verified Markdown links resolve and that the content reflects the current state of both projects per their respective documentation and source code. -- This is an automated message from the Apache Git Service.
