Phase 2: Fix triggers & dialogue — per-channel cooldowns, tension rebalance, user-message triggers

- Changed cooldown from global (ALL channels blocked) to per-channel dict keyed by channel_id
- Added conversation streak tracker: 3 near-miss interjection scores in a row force a dialogue trigger
- Expanded topic relevance keywords: added enthusiasm/vulnerability for Evil Miku, provocation/dismissal for Miku
- Lowered keyword divisor from /3.0 to /2.0 for higher base trigger scores
- Tension rebalance: added natural decay (-0.03/turn), reduced escalation weight (0.08->0.05), increased de-escalation weight (0.06->0.08)
- Reduced momentum multiplier (1.2->1.1) and intensity multiplier (1.3->1.2)
- Added spike cooldown: if last turn tension delta >0.15, next delta halved (prevents runaway spirals)
- Added user-message interjection check in bot.py on_message() (was only checking bot's own messages)
- Added random 15% argument trigger roll on user messages in normal message flow (was only from autonomous.py)
