   Fix #40256 
   
   - Set an explicit contextClassLoader on `JobInvoker`, `SparkPipelineRunner`, 
and `SparkContextFactory` threads so subsequent jobs do not inherit a closed 
Spark `ExecutorClassLoader` leaked onto shared `grpc-default-executor` threads.
   
   - Skip `SparkConf.setJars` in `SparkContextFactory` when running on a local 
Spark master (`local`, `local[N]`, `local[*]`, `local[N,M]`), avoiding copying 
classpath JARs into temporary per-context `userFiles` directories that are 
deleted when the `SparkContext` stops.
   
   - Broaden `SparkCommonPipelineOptions.isLocalSparkMaster` to match all local 
master variants (`local[*]`, `local[N,M]`) and add unit test coverage in 
`SparkPipelineOptionsTest`.
