ww: clean per-pid sep-build scratch dir on run/test (#59)

Browse Source 
ww run / ww test created /tmp/ww_{run,test}_<pid>.sepwork/ but removed only
the built binary, leaking the scratch DIR every invocation — the tmpfs filler
(98,811 entries blocked the gate twice). Add a keepscratch param to
build_one_sep: a thin wrapper rm -rfs the impl scratch at the single
choke-point when keepscratch==0 AND the path ends ".sepwork" (covers every
return, success+error; fires post-link, pre-run). do_build keeps it (the
byte-id gates read <stem>.sepwork from ww build -o); do_run/do_test clean;
do_test no-o redirects scratch into /tmp. Both stages symmetric; reuses the
existing shell rm -rf idiom (lib/os.removeall = #109). Test 989_sepscratch_run
is self-scoped by child pid (non-flaky) with a KEEP control + revert-verified
non-vacuity. Full gate: 448 pass, zero new run/test leaks. (ww_d_* relic +
historical bulk = one-time sweep + agent-probe discipline, not code.)
