Hojun-Cho d1ac836fb9 wcc/check: #24-sib reject array-payload tagged-union construction, both stages ...

Constructing an array-typed payload into a tagged-union variant silently
dropped it (cstage MOVQ $0 -> returns 0; wwstage match-loud only). Reject
the construct when the selected variant chases to TY_ARRAY (target
TY_TAGGED, non-tagged source). tagged-struct/slice/scalar/str variants and
the array TYPE-decl stay legal. Faithful array-into-box block-store
deferred (#6). test/wcc/834 (new) + Makefile.
