Is your feature request related to a problem? Please describe.
Currently, Auron can accelerate Iceberg scans only when the planned FileScanTasks do not contain delete files. For Iceberg Merge-On-Read tables, Auron falls back to Spark's Iceberg reader instead of using the native execution engine.
This prevents Auron from accelerating common Iceberg V2 MOR workloads, especially tables with row-level deletes, updates.
Describe the solution you'd like
Add native Iceberg MOR read support to Auron.
The preferred approach is to keep Iceberg Spark responsible for catalog access, snapshot planning, partition pruning, and producing FileScanTasks, then serialize the planned Iceberg scan tasks to the native engine. The native side should use iceberg-rust to read Iceberg Parquet data files and apply supported delete files correctly.
