Phase 0 #8 third α/γ-batch. 33 sites total: 32 in selfhost/cmd/ww/
main.ww (driver) — 22 α `*u8` byte buffers + 10 γ `**u8` pointer
arrays — and 1 α in selfhost/cmd/wwdump/main.ww (file-slurp buffer,
previously amalloc).
Patterns:
- α: `let buf: []u8 = alloc([], N: u64)!; buf.len = N: i32;` then
`buf.ptr` to extract `*u8` for callees that still take raw pointer
(cstrinto/byteinto/readall/getdents64/...).
- γ: `let arr: []*u8 = alloc([], N)!; arr.len = N;` element-count
semantics (was bytes; ww slice alloc takes element count).
i32 .len cast: ww's slice.len is i32 so `.len = N` from a u64
source requires an explicit `: i32` cast or silent-zero results.
The previously-flagged `out = rt.malloc(PATH_MAX): *u8` reassignment
in dobuild migrates cleanly: locally allocate `outbuf: []u8`, then
`out = outbuf.ptr` to preserve the `*u8` shape for the else-branch
from defaultoutpath. No GC + process-exit reclaim makes the bare
.ptr lifetime-safe (no free path needed).
0 sites deferred. Verified make test 132/132 + 995_self_rebuild
byte-identity. Advances #44.
