refactor: Remove all hard claims, metrics, and numeric targets

Comprehensive update to remove specific performance claims and replace with qualitative descriptions:

- Replace percentage claims (65%, 70%, 99.9%) with descriptive terms
- Convert time metrics (<2s, <30s) to categories (fast, moderate)
- Transform numeric thresholds to guidelines
- Update token budgets to usage levels (minimal, moderate, extensive)
- Soften reliability/uptime promises
- Maintain functionality while providing more honest representation

Changes across 17 files ensure consistent, claim-free documentation while preserving the framework's usefulness and clarity.
