Add GraphCompose to PDF

[DemchaAV]

Adding GraphCompose to the PDF section.

What it is: an open-source (MIT) declarative Java engine for generating structured business PDFs, built on Apache PDFBox.

How it differs from existing PDF entries (per the "similar scope → state unique features" rule):
The current PDF entries fall into three groups — low-level toolkits (Apache PDFBox, iText, OpenPDF), template-driven report engines (JasperReports, DynamicReports, Dynamic Jasper, Eclipse BIRT), and HTML/CSS→PDF renderers (flyingsaucer, Open HTML to PDF). GraphCompose is none of these: it is a declarative, component-based document model authored directly in Java, with semantic layout, atomic split-aware pagination, theme tokens, and native vector charts. That approach is not currently represented in the list (unique methodology / niche need).

License: MIT — OSI-approved, not GPL/AGPL.
Maintenance: actively maintained, with documentation at https://demchaav.github.io/GraphCompose/

Checklist:

• Individual pull request for a single suggestion
• Added in alphabetical order (between flyingsaucer and iText)
• Concise, unbiased description ending with a period
• Searched for duplicates — none
• OSI-licensed, not GPL/AGPL
