jgrusewski e393a8af89 chore(cleanup): Cleanup Wave 3 - Archive reports, organize docs, fix security issues
## Summary
Third major cleanup wave after investigating 287 remaining root files.
Archived historical reports, organized documentation, removed regeneratable
artifacts, and fixed critical security issue.

## Files Cleaned (119 total)
- Archived: 78 files (7 WAVE reports + 71 summaries) → docs/archive/
- Archived: 7 build logs → docs/archive/build_logs/
- Organized: 10 markdown files → docs/guides/ + docs/checklists/
- Deleted: 17 test/coverage artifacts (regeneratable)
- Deleted: 7 empty/obsolete files (docker override, clippy baselines)
- Deleted: 3 large files (119MB - .venv, ppo_hyperopt_output.txt, backup)

## Space Recovered
- Total: ~120.7 MB
- Large files: 119.25 MB (.venv, ppo_hyperopt_output.txt)
- Archives: 1.04 MB (summaries + build logs)
- Test artifacts: 980 KB

## Security Fix (CRITICAL)
- Fixed: certs/security.env removed from git tracking (contained JWT secrets)
- Updated: .gitignore to prevent future tracking of sensitive cert files
- Removed: 4 files from git history (security.env, production.env.template, *.serial)

## Documentation Organization
- Created: docs/archive/ (wave_reports/, summaries/, build_logs/)
- Created: docs/guides/ (7 detailed implementation guides)
- Created: docs/checklists/ (3 operational checklists)
- Retained: 30 essential .md files in root (quick refs, CLAUDE.md)

## Investigation Reports Created
- MARKDOWN_ORGANIZATION_REPORT.md
- TXT_FILES_INVENTORY_AND_ARCHIVAL_PLAN.md
- ROOT_CONFIG_FILES_ANALYSIS_REPORT.md
- DOCKER_ROOT_FILES_ANALYSIS.md
- DATABASE_INITIALIZATION_AND_SETUP_ANALYSIS.md
- (6 additional investigation/index files)

## Cleanup Wave Progress
- Wave 1: 899 files deleted (1,071,884 lines)
- Wave 2: 543 files archived/deleted (~34GB)
- Wave 3: 119 files archived/deleted/organized (~121MB)
- Total: 1,561 files cleaned, ~35.1GB space recovered

## Result
Root directory: 287 files → ~180 files (excluding investigation reports)
Clean, organized, production-ready structure maintained.

CRITICAL SUCCESS FACTORS:
1. ✅ Consolidate on ONE feature extractor (UnifiedFeatureExtractor)
2. ✅ Validate features during backtesting (not just predictions)
3. ✅ Use same features as live trading (SharedMLStrategy)
4. ✅ Compare Wave A/B/C sequentially (not isolation)
5. ✅ Test on real market data (DBN + real edge cases)
TIMELINE: 3 weeks (5 engineers working in parallel)
STATUS: READY TO IMPLEMENT (all components exist, just need integration)
