docs: fix README — align with current implementation

- Move RockEnvironmentConfig to trial/config.py in file structure diagram
- Remove duplicate environment: EnvironmentConfig from class diagram
- Fix syntax errors in code examples (env: → env={)
- Fix envs → env in 6.2 model_copy example
- Fix stale sandbox_config in 3.3 async example
- Fix OssRegistryInfo import (from rock.sdk.agent directly)
- Fix environment field type in harbor fields table
