v0.3.2 - Table Header Positioning Bug Fix

🐛 Bug Fixes

Table Header Positioning (Critical Bug Fix)

Fixed a critical bug where table headers were rendering below data rows instead of above them.

Root Cause:
Incorrect handling of PDF coordinate system where Y-axis grows upward from the bottom of the page.

Solution:
Comprehensive coordinate system overhaul in Table.ts affecting 8 critical locations:

• Changed rect(x, y, width, height) to rect(x, y, width, -height) for downward drawing (3 locations)
• Inverted calculateTextY() logic to properly position text in downward-drawing cells
• Fixed header border Y position from y + height to y - height
• Fixed row border Y position from y + height to y - height
• Corrected vertical border drawing direction
• Rewrote outer borders logic to properly handle top/bottom/left/right borders

✅ Testing

• Added comprehensive table test suite with 39 new unit tests
• Total test count increased from 229 to 268 tests
• All tests passing (268/268) ✓
• Coverage includes: basic rendering, column handling, styling, alignment, borders, page breaks, edge cases
• Browser compatibility verified with test-tables-browser.html
