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

Browse Source 
The try-operand resolution used bare lookups (ident + bare-leaf call);
a cross-module same-leaf collision mistyped the operand. Prefer the
current module. The historic 995 byte-id break attributed to this swap
was contamination from the guard-bug-carrying bundle — re-probed clean
in isolation and at the full stack. The N_DOT module-keyed leaf stays
task #51. Report item [11], lookup half.
