feat: add Java JRXML-to-PNG rendering pipeline with pixel-level SSIM comparison

- lib/java/: Java renderer (JrxmlRenderer) using JasperReports 6.21.0 - JrxmlDebug for diagnostics, JrxmlGen for format reference - download_jars.sh for one-time dependency setup - agent/nodes.py: _render_jrxml_to_png() and _compute_pixel_similarity() - Pixel comparison integrates into validate node (SSIM < 0.4 fails) - Pixel fidelity context injected into correct_jrxml for targeted fixes - tests/test_pixel_comparison.py: 15 unit tests (render, SSIM, integration) - .gitignore: exclude lib/java/*.jar, lib/java/*.class, tmp/ - CLAUDE.md: v11 changelog documenting the rendering pipeline - All non-LLM tests pass (97/97)
