feat(v0.2.1): data confidence tracking + validation + blog feedback system
- Migration 016: data_confidence column (vendor_verified/enriched_estimated/scraped_unverified)
- Migration 015: blog_feedback table with 8 quality scores + free text
- Validation script: 8 physics-based rules (wavelength↔fiber, reach plausibility, power limits)
- Blog feedback API: POST /api/blog/:id/feedback + training data export
- FO Blog Pipeline v3: 10-step Flexoptix Style prompts (Less bullshit. More engineering.)
- Auto-fix: wavelength↔fiber mismatches corrected automatically
