chore: comprehensive project reorganization and cleanup

## Critical Fix
- fix(docker): add missing COPY crates/ directive to Dockerfile
  Resolves CI build failure where workspace member ovsm was not copied
  into Docker build context

## Cleanup (Untracked Files Removed)
- Remove temporary log files (*.log, agave-validator-*.log, osvm_chat_*.log)
- Remove chat export JSON files (osvm_chat_export_*.json)
- Remove large text dumps (snapshot_*.txt, stderr.txt, stdout.txt)
- Remove temporary Python/shell scripts (complete_*.py, fix_*.sh, generate_qa.py)
- Remove screenshot files (osvm-docs-*.png)
- Remove ledger directories (*-ledger/)
- Remove backup HTML files from docs/ (index*.bak, index-old.html, index-new.html)

## Documentation Reorganization
- Archive session summaries to docs/archive/session-notes/
  * AI_CONTEXT.md
  * SESSION_SUMMARY.md
  * QA_PROGRESS_REPORT.md
  * UI_ENHANCEMENTS.md
  * ULTIMATE_DECODER_SUITE.md
  * FINAL_SESSION_SUMMARY.md (untracked)
  * FINAL_TEST_STATUS.md (untracked)

## test_qa_categories/ Cleanup
- Archive 16 redundant status files to archive/
  * Multiple "FINAL_*" variants (FINAL_STATUS, FINAL_VALIDATION, etc.)
  * Validation reports (VALIDATION_REPORT, VALIDATION_REPORT_V2)
  * Generation/fix summaries
  * Keep: README.md, INDEX.md, QUICK_REFERENCE.md, actual QA files

## crates/ovsm/ Cleanup
- Archive 11 assessment/bug report files to docs/archive/
  * Assessment files: *ASSESSMENT*.md, *STATUS*.md, *SUMMARY*.md
  * Bug reports: BUG_*.md
  * Keep: README, CHANGELOG, HOW_TO_USE, USAGE_GUIDE, user-facing docs

## Script Organization
Root scripts moved to scripts/ subdirectories:
- scripts/deps/ - dependency update scripts
- scripts/dev/ - development utilities (local RPC, tunnel manager)
- scripts/build/ - build scripts (Docker, rootfs, unikraft)
- scripts/setup/ - environment setup
- scripts/demo/ - demo scripts
- scripts/validation/ - validation scripts

scripts/ directory organized:
- scripts/test/ - test scripts
- scripts/setup/ - setup scripts
- scripts/debug/ - debug utilities
- scripts/benchmark/ - performance benchmarks
- scripts/qa/ - QA generation scripts
- scripts/build/ - build scripts within scripts/

## Verification
- ✅ cargo check passes (warnings only, as expected)
- ✅ Project structure validated
- ✅ 52 files reorganized
- ✅ Git history preserved via git mv

## Impact
- Cleaner root directory (reduced clutter)
- Organized script structure (improved discoverability)
- Archived historical documents (preserved but not prominent)
- Fixed CI blocker (Docker build)
- No breaking changes to functionality

Addresses user request for codebase reorganization and doc sync.
