~x-ai/grok-latest → A (2:1)

A removes a real dead-code path in apply_vote and fixes the negative-ratio test to the actual contract (items/pairs registered; zero-weight edges skipped by add_edge_weight), tightening core vote semantics. B only deletes the leftover monolithic forum.rs and reshuffles the same HTML into forum/* modules—including large near-copies of feed/views/profile—so its value is structural cleanup, not new behavior.
