`let x: [2]inner = [inner{..}, inner{..}]` left the array unpopulated:
the N_ARRLIT per-element store handled scalar/str/float ONLY, so a
struct/array/tuple element hit the multi-word-store gap and stored just
the first 8 bytes (cs0/ww0). Both stages symmetric-broken; converge on
the populated result (#263).
Fix: an aggregate element of an array literal fills each element slot
from its source — cg_structlit_fill_bp for an N_STRUCTLIT element,
word-copy for an N_IDENT element (reusing COMMIT 2's per-element copy
shape). esz is the element's natural size (cstage esub->size). cgen.c
N_ARRLIT arm + cgenstmt.ww cglet. An aggregate `...` repeat and other
element shapes hard-stop loud (rule-7).
949 rows: arrlit_structlit, arrlit_structident (8B struct, byteid=1,
full readback). All 96 pass; test-unit 241 green; smoke OK.
