Hojun-Cho 03b7336cae selfhost/cmd/wcc + lib/strings: restore SSoT routing for str/slice tinfo helpers ...

Phase A.5's tupleelemslot / fieldslotsize hardcoded 16u64 for TY_STR
and 24u64 for TY_SLICE — bypassing the tinfo.size SSoT seeded by
lib/ww/typ.ww:189 (the very pivot they were introduced to consult).
Route those four arms through pt.size / ft.size so #1 (str→24) and
#34 (slice graduation) land as a one-line bump at the seed.

lib/strings/stringstest.ww carried 12 `(cap: u64) * 16u64` strides
missed by #43's sweep over strings.ww + shlex.ww; convert to
`* size(str): u64` so the #42 fold owns the constant. Doc comments
in strings.ww (freeall + splitn) updated to the same SSoT form.

No-op at today's str.size=16 / slice=24: tinfo.size already matches
the literals these arms had baked in. Reviewer's pre/post asm-identity
probe (struct{i64,str,i64} + (i32,str,i32) tuple + bare str) shows
zero-byte diff. 131/131 + 994 + 995 + bootstrap (ww2==ww3==ww4) green.

Forward-link to #1 (str→24B bump) and #64 (sizelint pre-commit gate);
#65 filed for lib/bytes + lib/getopt sibling sites the reviewer
surfaced. Forward of #64 will catch any future regressions of this
class.
