fix: resolve package conflicts and update documentation

- Move main package files to benchmarks/cmd/ to fix test failures
- Update CLAUDE.md with comprehensive benchmarking and profiling instructions
- Fix unused imports in serverless.go
- Remove experimental buffered pipe/copy implementations
- Remove outdated documentation files

All integration tests now pass successfully.
