Paragraphs now flow as continuous text, with only actual paragraph
breaks (large Y gaps) creating newlines between them.

Drop caps are large decorative first letters that span multiple lines.
Due to PDF coordinate sorting, they often appear after the text they
belong to. This change:
- Detects drop caps: single uppercase char with font size >= 2.5x base
- Finds the paragraph start (first lowercase-starting line after header)
- Merges the drop cap with that line
Example: "G" + "lenair brings..." -> "Glenair brings..."

Major changes:
- Switch from lopdf.extract_text() to position-aware extraction
- Text is now sorted by visual reading order (top→bottom, left→right)
- Fixed font size calculation to account for text matrix scaling
- Headers are now detected based on font size ratios
- Skip very short text (≤3 chars) for header detection to avoid drop caps
This significantly improves output quality for PDFs with complex layouts.
Before: Title appeared at end, no structure detected
After: Correct reading order, headers marked with # syntax
