Hojun-Cho 9cceb4ca8d wcc/ww: loud dep_cycle reject + #31 dup-symbol gate (M3-tail c4, #46) ...

Promote commit-3's tri-color topo bail into a loud dep_cycle error that names the full import cycle, byte-identical both stages (cmd/ww/main.c + selfhost/cmd/ww/main.ww, deps.ha:243 parity).

Add a non-vacuous negative gate (989_sepcycle_dup) proving the pre-existing w6l duplicate-symbol reject fires loud + non-zero on a cross-package collision; no new linker code.

#58(b)(c) link-arg parity deferred (system()-string vs procrun()-argv is structurally un-unifiable in this scope); #61 filed for the byte-id-blind w6l_ww dup-message divergence.
