feat: add configurable work directory with default ~/git/gitsyncer-workdir

- Add work_dir field to configuration file
- Set default work directory to ~/git/gitsyncer-workdir (avoiding conflict with source repo)
- Support home directory expansion (~/) in work_dir config
- Command-line --work-dir flag takes precedence over config file
- Automatically create work directory if it doesn't exist
