TotemSense

Release notes:
- Added Shaman-only alert display: TotemSense can stay enabled on other classes without showing totem notifications.
- Significantly expanded the internal NPC and ability database.
- Maintains the core TotemSense behavior: pre-cast warnings based on target, focus, mouseover, and visible enemy nameplates.
- Preserves the learning behavior from prior versions, allowing the addon to learn additional NPCs during gameplay when supported effects are detected.
- Continues to suppress warnings while the matching cleansing totem is active, and re-alerts when the totem expires, is destroyed, or is replaced.
