docs: Major documentation cleanup and accuracy fixes for 1.0

✨ RESTORED the 9th method - augment() for infinite extensibility!

REMOVED (20 files):
- All business strategy and revenue projection documents
- Misleading Cortex CLI documentation
- Outdated duplicate documentation
- Internal technical analysis files

FIXED:
- ✅ Corrected to 9 unified methods (was incorrectly showing 8)
- ✅ The 9th method `augment()` enables methods 10→∞
- ✅ Removed non-existent CLI commands (add-noun, add-verb)
- ✅ Brain Cloud marked as "Early Access" with real pricing
- ✅ Aligned with actual soulcraft.com offerings
- ✅ All code examples now match actual implementation

CONSOLIDATED:
- Combined 3 augmentation docs into single AUGMENTATIONS.md
- Removed duplicate quick-start guides

ADDED:
- cleanup-git-history.sh script for removing sensitive files from history
- Clear Brain Cloud pricing tiers ($19 Cloud Sync, $99 Enterprise)
- Transparency about optional services sustaining development

All documentation is now accurate, honest, and appropriate for an MIT
open source project with optional cloud services.
