Add game channel redirect feature and sexual_vulgar detection

Detect when users discuss a game in the wrong channel (e.g. GTA talk
in #warzone) and send a friendly redirect to the correct channel.
Also add sexual_vulgar category and scoring rules so crude sexual
remarks directed at someone aren't softened by "lmao".

 - If a message contains BOTH a nickname AND an insult ("fuck you tits you piece of shit"), score the insult, not the nickname.
 - If the target message is just "lmao", "lol", an emoji, or a short neutral reaction, it is ALWAYS 0.0 regardless of what other people said before it.
 - If a user is QUOTING or REPORTING what someone else said (e.g. "you called them X", "he said Y to her"), score based on the user's own intent, NOT the quoted words. Tattling, reporting, or referencing someone else's language is not the same as using that language aggressively. These should score 0.0-0.2 unless the user is clearly weaponizing the quote to attack someone.
+- Sexually crude or vulgar remarks DIRECTED AT someone (e.g. "you watch that to cum", "bet you get off to that") = 0.5-0.7 and category "sexual_vulgar". Adding "lol" or "lmao" does NOT soften sexual content aimed at a person — it's still degrading. General sexual jokes not targeting anyone specific can score lower (0.2-0.3).
+- "lol"/"lmao" softening ONLY applies to mild trash-talk and frustration. It does NOT reduce the score for sexual content directed at someone, genuine hostility, or targeted personal attacks.
 
 Also determine if the message is on-topic (gaming, games, matches, strategy, LFG, etc.) or off-topic personal drama (relationship issues, personal feuds, venting about real-life problems, gossip about people outside the server).

+GAME DETECTION — If CHANNEL INFO is provided, identify which specific game the message is discussing. Set detected_game to the channel name that best matches (e.g. "gta-online", "warzone", "battlefield", "cod-zombies") using ONLY the channel names listed in the channel info. If the message isn't about a specific game or you're unsure, set detected_game to null.
