1. Word Fragment Joining (extractor.rs:63-94)
Added is_word_continuation() to detect when text items are fragments of the same word and should be joined without spaces:
2. Caption Detection (markdown.rs:621-658)
Added is_caption_line() to detect figures, tables, and source citations:
- Ensures captions are on their own line with paragraph breaks
3. Paragraph Threshold Adjustment
Changed from base_size * 2.0 to base_size * 1.8 for better paragraph detection.
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

The previous code used `trimmed.len() >= 2` to check if there were at
least 2 characters, but `len()` returns byte count, not character count.
For multi-byte UTF-8 characters (e.g., "é" which is 2 bytes), this check
would pass but `chars().nth(1)` would return None, causing a panic.
Fixed by using iterator pattern matching to safely extract the first
two characters.
