Improve combo point duration tracking system

Major enhancements to the combo point finisher tracking system:

**ComboPointTracker.lua:**
- Added spell ID-based tracking (ComboScalingSpellsByID table)
- All Rupture ranks (1943, 8639, 8640, 11273, 11274, 11275): 8s + 2s per CP
- Kidney Shot ranks (408, 8643): Rank 1: 1s + 1s per CP, Rank 2: 2s + 1s per CP
- Druid Rip ranks (1079, 9492, 9493, 9752, 9894, 9896): 12s + 4s per CP (corrected from 10s + 2s)
- New TrackComboPointCastByID() function for UNIT_CASTEVENT integration
- Initialize spell_tracking table to prevent nil errors
- Consistent debug output using CleveRoids.debug flag

**Utility.lua (libdebuff integration):**
- UNIT_CASTEVENT handler now checks combo scaling spells first
- Calls TrackComboPointCastByID() before normal duration lookup
- Learning system skips combo spells (they're dynamically calculated)
- Improved debug messages distinguish combo spells from regular spells

**Core.lua (console commands):**
- Added /cleveroid combotrack - Display recent combo finisher casts
- Added /cleveroid comboclear - Clear combo tracking data
- Updated help text with combo point tracking section

**README.md:**
- New "Combo Point Scaling" section with examples
- Updated settings documentation with new commands
- Added /cleveroid debug to settings list
- Example macros showing combo point-aware debuff conditionals

This system ensures accurate duration tracking for:
- Rogue: Rupture (8-16s), Kidney Shot (1-6s)
- Druid: Rip (12-28s)

All durations are now calculated based on actual combo points used at cast time.
