MidnightNameplates 0.11.0 - Phase 11.0 PvE Intelligence Foundation

PURPOSE
Builds the framework for Mythic+/Raid intelligence without shipping guessed or copied dungeon data.

NEW
- Intelligence config page.
- Context detection:
  Open World / Dungeon / Mythic+ / Raid / Other.
- Optional instances-only behavior.
- HIGH/CRITICAL NPC rule emphasis.
- HIGH/CRITICAL spell rule emphasis.
- Separate scale values for HIGH and CRITICAL NPCs.
- Cast pulse/glow flags prepared for visual-alert implementation.
- Uses existing user-created NPC/spell rules and priorities.

HOW TO TEST
1. Create an NPC rule for a dungeon mob and set priority HIGH.
2. In a dungeon, verify the mob receives the HIGH-priority scale emphasis.
3. Change rule to CRITICAL and verify stronger emphasis.
4. Create a spell rule with HIGH/CRITICAL priority.
5. Verify the cast is marked internally as high/critical and existing rule styling still applies.
6. Disable Intelligence -> behavior returns to normal rule styling.
7. Enable Instances Only -> open-world rules should not receive PvE intelligence emphasis.
8. Profiles, import/export, friendly-player auras and mailbox filtering remain unchanged.
9. No Lua/taint/secret-value errors.
