chore: prepare v1.0.0 release — docs, CI, and GitHub presence cleanup

- Add CHANGELOG.md and SECURITY.md for release readiness
- Update CI workflows from actions v2 to v4/v5 (Node.js 16 deprecation)
- Fix CONTRIBUTING.md clone URL (your-org → YichengYang-Ethan)
- Fix pyproject.toml classifier (Alpha → Beta to match v1.0.0)
- Rewrite docs/index.md and PROJECT_SPECIFICATION.md (remove outdated
  Social World Model references, align with current Solana architecture)
- Update mkdocs.yml site_description to match on-chain agent focus
- Add Release badge and Contributing/Security sections to README
- Remove internal issue templates (codebase_reorg, exp_record, writing_task)
- Remove unused assets/readme_title.svg
- Disable empty GitHub wiki
