### Purpose This is a subtask of [MAP shared-shredding support](https://cwiki.apache.org/confluence/display/PAIMON/PIP-43%3A+Columnar+Storage+Optimization+for+MAP+Type+in+Paimon). Add append table read/write support for MAP shared-shredding. This wires MAP shared-shredding into the append write path and ORC/Parquet read path, keeps the format layer working with physical read rows, and converts them back to logical MAP rows through the shredding read plan. It also adds end-to-end coverage for basic read/write, multiple shared-shredding MAP fields, projection, data evolution, metadata recovery, null values, overflow values, and complex value types. ### Tests - `mvn -pl paimon-common,paimon-core -am -Pfast-build -DfailIfNoTests=false -DwildcardSuites=none -Dtest=MapSharedShreddingReadPlanTest,AppendOnlyWriterTest test` - `mvn -pl paimon-core -am -Pfast-build -DfailIfNoTests=false -DwildcardSuites=none -Dtest=MapSharedShreddingTableTest test` - `mvn -pl paimon-common,paimon-core -am -DskipTests spotless:apply` - `git diff --check` -- This is an automated message from the Apache Git Service.
