#### Which Delta project/connector is this regarding? <!-- Please add the component selected below to the beginning of the pull request title For example: [Spark] Title of my pull request --> - [ ] Spark - [ ] Standalone - [ ] Flink - [ ] Kernel - [ ] Other (fill in here) ## Description Added a new UC E2E streaming test suite to cover Delta structured streaming read/write behavior across managed/external tables, including UC commit version validation for managed tables. The changes live in spark/unitycatalog/src/test/java/io/sparkuctest/ UCDeltaStreamingTest.java to exercise MemoryStream writes, streaming reads in V2 strict mode, and checkpointed queries. <!--⚠️ ⚠️ **Note to reviewers**⚠️ ⚠️ this branch is based on delta-io#5651; therefore there are a number of changes that are not directly related to the E2E test integration for streaming reads (those changes are to enable these streaming reads).
