chore: Major cleanup - archive migration scripts and remove temp files

CLEANUP ACTIONS:
- Archived 11 migration/optimization scripts to archive/migration_scripts/
- Archived 11 phase documentation files to archive/documentation/
- Moved backups/, docs/, scripts/ to archive/
- Deleted 30+ temporary debug/test/fix scripts
- Cleaned Python cache (__pycache__/, *.pyc)
- Cleaned log files (*.log)

NEW FILES:
- CHANGELOG.md: Consolidated project history and migration documentation
- Updated .gitignore: Added *.log, *.pyc, archive/ exclusions

FINAL ROOT STRUCTURE (19 items):
- Core framework: agent.py, autonomous_agent_demo.py, client.py, security.py, progress.py, prompts.py
- Config: requirements.txt, package.json, .gitignore
- Docs: README.md, CHANGELOG.md, project_progress.md
- Directories: archive/, generations/, memory/, prompts/, utils/

ARCHIVED SCRIPTS (in archive/migration_scripts/):
01-11: Migration & optimization scripts (migrate, schema, rechunk, vectorize, etc.)

ARCHIVED DOCS (in archive/documentation/):
PHASE_0-8: Detailed phase summaries
MIGRATION_README.md, PLAN_MIGRATION_WEAVIATE_GPU.md

Repository is now clean and production-ready with all important files preserved in archive/.
