feat: integrate task directory store into execution flow

- Use taskDirectoryStore for directory resolution in initializeRepoPath()
- Persist directory mappings when setRepoPath() is called
- Save repo→directory mapping after clone completion
- Support tasks without repository_config

Enables per-task directory customization and repo sharing across tasks.
