Next.js 16 truncates request bodies at 10MB in middleware layer,
causing ECONNRESET for large PDF uploads. Set middlewareClientMaxBodySize
to 500mb to allow large file uploads to reach the route handlers.

formData() fails with "Failed to parse body as FormData" on large PDFs
in Next.js route handlers. Switch to req.arrayBuffer() which reliably
reads the full body, then manually extract the PDF from multipart.
Extreme mode: arrayBuffer + multipart extraction + GS + qpdf pipeline.
Stirling mode: arrayBuffer forwarding to Stirling with proper headers.
Revert serverActions.bodySizeLimit (doesn't apply to route handlers).

Extreme mode: replace fragile manual multipart boundary parsing (which
extracted only a fraction of large files, producing empty PDFs) with
standard req.formData(). Add GS output validation + stderr capture.
Stirling mode: parse formData first then build fresh FormData for
Stirling instead of raw body passthrough (which lost data on large
files). Add 5min timeout + original/compressed size headers.
next.config: add 250MB body size limit for server actions.
