docling convert-remote

Convert documents through a remote docling-serve service instead of locally.

Sources may be local files, local directories (walked and filtered by --from), or http(s) URLs. Results are written to --output in the formats given by --to, identical to docling convert. Only options the service honors are exposed here; local-execution flags (device, threads, pdf-backend internals, debug visualizers) do not apply to remote conversion and are intentionally absent.
