Refactor importers to use FileService for all file operations instead of
direct filesystem calls. This enables cloud environments to override file
operations via dependency injection (e.g., S3FileService).
Changes:
- Add `to_markdown_string()` method to MarkdownProcessor for content
serialization without file I/O
- Update Importer base class to accept FileService and use it for:
- `write_entity()` - now uses FileService.write_file()
- `ensure_folder_exists()` - now async, uses FileService.ensure_directory()
- Fix direct `mkdir()` calls in:
- claude_projects_importer.py
- memory_json_importer.py
- Update deps.py to inject FileService into all importers (v1 and v2)
- Update CLI commands to create and pass FileService to importers
- Update tests to work with new FileService dependency
This follows the pattern used by /knowledge API and SyncService, enabling
cloud to override file operations by providing S3FileService via DI.
