chore: add install scripts, doctor command, and AGENTS.md
All checks were successful
ci/woodpecker/push/infra Pipeline was successful
ci/woodpecker/push/api Pipeline was successful

- Add one-line installer (scripts/install.sh) with platform detection
- Add doctor command (scripts/commands/doctor.sh) for environment diagnostics
- Add shared libraries: dependencies, docker, platform, validation
- Update README with quick-start installer instructions
- Add AGENTS.md with codebase patterns for AI agent context
