Hojun-Cho 2c62be44a7 test/wcc: 989_declns_sep decl-namespace gate — dup reject / builtin redecl / dir-pkg modfn coexist (M4 E2-C2c, #22) ...

Final E2-C2 commit. New decl-namespace gate, both stages: dup fn/type/def/let build-FAIL with a right-reason "duplicate <kind> <name>" diag (shared substring; ww has no line:col); builtin_redecl ACCEPT exit 7 (shadowing a pre-seeded builtin is redeclarable); modfn coexist reshaped to a real directory package (696 precedent) via ww build --sep on two layouts (modfn_coexist + _vbu use-before-value) so both run to 6, cs==ww per-pkg .s/.wwi/.unit.ww, cross-order byte-id on .s/.wwi (.unit.ww excluded: verbatim source flips by construction, order-independence is codegen). __root.s carries both CALL aa.helper and CALL main.aa distinctly. Test-only; all 5 pins hold; 443 to 444.
