Route Paimon tables marked with lakestream.enabled to the Fluss Spark catalog and cover log and primary-key table reads and writes on Spark 3.4 and 3.5.

Use the published Fluss Spark 2.12 connector test artifacts for all builds because Scala 2.13 snapshots are unavailable. Skip MiniCluster integration tests under Scala 2.13 while keeping catalog routing tests enabled.

Keep Java 11 Fluss test artifacts off the Spark 3 Java 8 Surefire classpath and avoid initializing the MiniCluster below Java 11. Verify the optional connector behavior and run the Fluss read/write suites in the existing JDK 11 workflow.

Keep the Java 11 Fluss test classes out of JUnit Vintage discovery after excluding their runtime dependencies from the Java 8 Surefire classpath.

Read base Fluss LakeStream tables through Paimon while routing writes to Fluss. Expose $rt as a read-only Fluss union view and leave $stream unsupported. Keep catalog routing in spark.catalog and table adapters in spark.

We should provide standard abstractions to allow Fluss to be integrated via plugins, rather than hardcoding it. |

I'll push forward the PIP-39: Enable In-Place Upgrade of Existing Paimon Tables for Sub-Second Latency via Fluss to propose the abstraction/change for both flink and spark |

Purpose
Support reading and writing Fluss LakeStream tables through the Paimon Spark catalog.
FileStoreTables marked withlakestream.enabled=trueto a lazily initialized Fluss Spark catalog.fluss.*catalog options to Fluss while keeping create, alter, and drop behavior unchanged.1.0-SNAPSHOTfor the test dependencies because the stable release does not publish the required MiniCluster test jars.Tests
