* perf(pdf): native Pdfium-based reflow engine with auto-open
Migrate PDF-to-Markdown reflow generation from PDFBox to a custom
native implementation using Pdfium. This transition improves
processing speed by ~10x and significantly reduces memory overhead.

with bulk array retrieval (`getPageFontSizes`, `getPageFontWeights`),
drastically reducing JNI boundary overhead.

native font weight (bold) and relative font size variance (headers).
- Thread Safety: Refactored generator to process pages sequentially
while synchronized with the global `PdfiumCore.lock` to ensure
stability across concurrent UI operations.

PDF viewer that tracks user intent and navigates to the reflow
view immediately upon background task completion.
