--mode sync

Options
-------
* `--format md|json` (default: `md`)
  - Output format: Markdown or JSON
* `--mode sync|async` (default: `sync`)
  - Synchronous mode: waits for conversion to complete
  - Asynchronous mode: polls status until completion
* `--func METHOD` (default: `unisound`)
  - Conversion method/algorithm to use
* `--output DIR` (default: `./unidoc-output`)
  - Output directory for converted files
- 
* `--uid UUID` (optional)
  - Custom user ID (auto-generated if not provided)

Output conventions
------------------
* Creates `./unidoc-output/<document_name>/` by default
* Markdown output: `output.md`
* JSON output: `output.json`
* Output filename preserves original document name

Notes
-----
* Requires network connectivity to UniDoc API (http://unidoc.uat.hivoice.cn)
* Supports multiple file formats: PDF, DOC, DOCX, PNG, JPG, etc.
* Async mode polls every 1 second until completion
* Max file size and rate limits depend on API service configuration
* For large files or batch processing, prefer async mode
