feat(vibee-v10.5): Auto-Curation & Self-Feeding v2 - Phase 2 COMPLETE

Multi-stage validation system for synthetic seeds with self-feeding.

New CLI command:
  vibee curate-seeds   Auto-curate seeds through validation pipeline

Validation stages:
1. Syntax validation - balanced braces, non-empty body
2. Semantic validation - quality scoring based on characteristics
3. Pattern validation - anti-pattern detection (TODO, FIXME, @Panic)
4. Auto-approval - seeds with score ≥0.7 approved

Achievements:
- 34 original seeds all approved (100% pass rate)
- 425 $TRI earned (12.5 $TRI/seed average)
- Self-feeding: high-quality seeds auto-imported to Golden DB

φ² + 1/φ² = 3
