Which Dota 2 heroes got better or worse after the patch — winners/losers by win-rate shift. Compares each hero's win rate over the last 14 days vs the prior 14 days WITHIN the current patch — real trend data from batru.gg's match aggregation, not a guess. Useful for "what's getting stronger lately?" questions between patches. Args: hero: Optional — a specific hero to look up. Empty returns the top risers and fallers overview. limit: Max risers/fallers to return in overview mode (default 10). Returns {patch, window_days, data_through, ...} plus either one hero's {hero, wr_recent_pct, wr_prev_pct, delta_pp, n_recent, n_prev} or {risers:[...], fallers:[...]}. delta_pp is percentage-point change; small deltas (<1pp) are noise — say so rather than over-reading them. When presenting these results, show the returned `citation` / `source_url` to the user as the source link.
