PayInterrupt

Now uses event correlation rather than direct API reads in instanced combat:

UNIT_SPELLCAST_SUCCEEDED (player kick spell) → queues a pending cast
DAMAGE_METER_COMBAT_SESSION_UPDATED with type=Interrupts → fires the same frame as the kick
If there's a pending cast in the queue when that event arrives → confirmed interrupt, fire alert immediately

What this cannot do based on Blizzard's restrictions (at least currently):

• Show spell name/icon in combat when the notification fires
• Show creature/player name in combat when the notification fires

More updates coming:

• May deprecate log feature since it's not really doing anything Blizzard's damage meter doesn't do
• Will soon add ability to modify text for success or failure assuming this ends up working out the way I expect (current functionality is it only triggers at all on success, but some have noted it would be nice to get feedback the interrupt has at least gone off)
