wcc/ww: scopelookuptype prefers the current module's symbol

Browse Source 
A type lookup in a bundled build resolved to the newest-installed
same-leaf symbol from ANY module; prefer the current module first
(mirror cstage sym.c:131; the prior attempt's failure was its own
u64-vs-i32 guard bug, not a deeper layer — probe-proven). Also adds
the rule-7 #58 notes at the latent varianterr/scruttype pair and
rewrites the stale deferral block to closing cites. Report item [5].
