Build FStar only type-checks the compiler and ulib. Running `make test` afterwards exercises the tests/examples suite, which sends many more SMT queries to the freshly built Z3 and produces more logged failing queries for the existing .smt2 collection step. The new step runs in the FStar clone with the same opam env, PATH to the Z3 aliases and OTHERFLAGS as the build. It is gated on a new fstar_run_tests input (default true) and on the build succeeding, and is continue-on-error so a test failure does not hide the build result or skip reporting. The discussion summary reports the test outcome and the tail of the test log; the SMT2 preview budget is reduced accordingly to stay below the discussion body size limit.
