Phase 0 #8/#11 small batch. 4 sites:
w6l/main.ww δ stack-promotes (3):
- :67 appenddec — 16B → [16]u8
- :106 islinkable — 8B → [8]u8, &mp[0] to os.read
- :176 isso — 20B → [20]u8, &mp[0] to os.read
wcc/cgenutil.ww:108 mkvarargname α (1):
- amalloc → alloc([], n)!. Standard slice indexing
(`p[k]` not `p.ptr[k]`) — ww's slice subscript has no
bounds check (cgenexpr.ww:816-856 in cgindex), same
shape as the dup pilot (4c07ef0).
Closes #11 (arenau64tos was re-routed via #8 separately;
the δ-shape was the genuinely trivial case). Advances #46.
Verified 132/132 + 995_self_rebuild byte-identity.
