### Purpose Support Spark replace-table flows for Paimon tables while preserving table history where possible. This change adds staged replace support for `REPLACE TABLE` and `CREATE OR REPLACE TABLE ... AS SELECT`, using truncate plus schema replacement for compatible FileStore tables so old snapshots remain available for time travel. It also falls back to drop-and-create when the source or target is not a Paimon table, handles SparkGenericCatalog provider checks, and documents the Spark SQL behavior. ### Tests Added coverage for catalog-level replace table, Spark SQL replace table, create-or-replace-as-select, incompatible schema replacement, table existence errors, provider/table type fallback, and time-travel reads after replace. -- This is an automated message from the Apache Git Service.
