   ### What problem does this PR solve?
   
   Issue Number: close #xxx
   
   Problem Summary: `run-fe-ut.sh` does not support build concurrency or unit 
test execution concurrency. The FE `pom.xml` already supports the 
`fe_ut_parallel` variable (via `env.FE_UT_PARALLEL`) to control 
maven-surefire-plugin `forkCount`, but `run-fe-ut.sh` never passes this 
variable, defaulting to 1 JVM for unit tests. This makes FE unit test execution 
very slow.
   
   ### Release note
   
   Add `-j` and `-p` options to `run-fe-ut.sh` to support build parallelism and 
unit test parallelism respectively. `-j <num>` controls Maven build thread 
count (passed as `-T`), and `-p <num>` controls the number of forked JVMs for 
running unit tests (passed as `FE_UT_PARALLEL` env variable which maps to 
`forkCount` in maven-surefire-plugin).
