fix: use file parameter instead of getActiveFile() for embed processing

Fixes #95 where embedded markdown files were being missed when dealing
with large documents. The previous code used `getActiveFile()` which
could return undefined or the wrong file during async processing,
especially in batch export scenarios.

Now uses the `file.path` parameter which is the correct file being
exported, ensuring consistent behavior regardless of active file state.
