Hojun-Cho bdfb5cda58 wcc: route DATA-emit through emitsymname mangler (#127)
wwstage cgen.ww emitdefconstants now uses the same emitsymname
mangler that LOAD/CALL sites use, replacing 8 lines of duplicate
`d.exported`/`d.nmod` logic. Rule-12 sea-of-stars consolidation —
one path, not two parallel paths that can desynchronise.

Cstage twin: cmd/w6c/cgen.c:8510 (mod_mangle in emit_defs). Bootstrap-
neutral post-90d31c5 (the duplicate PATH_MAX def that motivated the
divergence was cleaned up in drew's source-hygiene fold); all 5 tool
combined.ww emit cs==ww byte-identical asm post-fix. New test 913
(4 rows: exported i64 def, main-local i64 def, u64 width, multi-def
sequence) pins the simple-shape invariant forward — a future caller
introducing a colliding name produces the same symbol from both
stages by construction.

Drew's (a) ruling. Reviewer-127 noted the new path additionally
consults FFI (ffiresolve) which the old d.exported/d.nmod block did
not — incidental improvement to cs/ww symmetry beyond the mod-mangle
consolidation.
