test: migrate Fam4 static-init/DATA-emit value tests to @test (#30)
Continues the test-arch tower past Fam8-13. 11 module-level static-init
/ DATA-emit value drivers move from test/wcc/*_run.c into @test row-
tables under test/lang/; every classification empirically re-probed at
HEAD (refuting two stale worklist tags).
- value rows -> test/lang/*_test.ww (11 files)
- reject rows -> runww //ww:error carriers (3, dual-stage non-vacuous;
947 const-divzero confirmed a both-stage compile-reject, not run-exit)
- 840_zeroinit, 944_array_zeroinit, 989_arrlit_tail_zero kept as byte-id
.c pins (zero-over-dirtied-frame / DATAW-length is byte-id-blind to a
runtime @test; #263), mutation-gated
- repoint two stale comment refs to deleted test names (719,
989_structlocal_frame)
Migrated static-init @test ride the cs==ww T2 byte-id gate, preserving
DATA-emit byte-id. 2D global-struct array-field read (#137/#150)
confirmed cs==ww + correct at HEAD. Coverage parity verified row-by-row;
two-round reviewed. Floor ratchet follows.
