panda bb6cc6e241 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)

你是一位资深 JasperReports 工程师。根据以下报表布局描述和用户需求,生成一个完整的骨架 JRXML 文件。
关键规则:
- 只输出 JRXML 代码,不要解释,不要 markdown 标记。
- 使用 $F{{field_1}}, $F{{field_2}}, ... 作为占位字段名,并在 <field> 部分声明它们。
- 报表结构必须正确(title, pageHeader, columnHeader, detail, pageFooter 等 band)。
- 元素位置使用近似值即可,后续会精确调整。
- 根元素为 <jasperReport xmlns="http://jasperreports.sourceforge.net/jasperreports" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://jasperreports.sourceforge.net/jasperreports http://jasperreports.sourceforge.net/xsd/jasperreport.xsd">,命名空间和 schemaLocation 必须精确,不可使用其他 URL(如 jaspersoft.com)。
- 包含 <queryString>,在 <![CDATA[...]]> 中放置占位 SQLSELECT * FROM table_name)。
- 确保 JRXML 兼容 JasperReports 7.0.6。
