fix(plugins): parse files when Dify already has an event loop - #3756

Summary

Fixes #3732

Knowledge pipelines that pass multiple files into LlamaParse fail with a type-confusion error or an async warning, and the plugin often reports success while emitting the error as text. Unstructured Transform hits the same worker constraint: asyncio.run() cannot be called from a running event loop.

LlamaParse 0.0.9

• Coerce each File.blob to bytes (bytearray / memoryview included) so load_data is not given a nested list or non-bytes payload
• Wrap load_data with nest_asyncio so parsing works inside the gevent plugin daemon
• Raise parse/download errors instead of yielding them as successful text output
• Normalize a single file into a list so multi-file source nodes keep working

Unstructured Transform 0.0.11

• Run _transform / credential checks through _run_coroutine(), which applies nest_asyncio before asyncio.run

Release Notes

• Fix: LlamaParse now accepts multiple knowledge-pipeline files, coerces file bytes, and fails the node when parsing errors instead of returning them as success text.
• Fix: Unstructured Transform no longer crashes with asyncio.run() cannot be called from a running event loop inside Dify workers.
