'ww test' gains the istest build path (-T injection in build_one/ buildone) and do_test/dotest accept -I, mirroring do_run - both twins. The 35 converted lib tests drop their interim bare mains (-T synthesizes the entry from @test fns and rejects a user main); their 35 C run-drivers flip 'ww run' -> 'ww test'; 989_lib_byteid compiles lib tests under -T (8 user-main probe fixtures stay non-T, gated on the fixture field). Abort-on-first-failure stands until the deferred record-and-continue harness lands with the multi-package arc.
