fix(frameworks): load standalone JPA relationship context

[xiehuanyi]

Summary

Load JPA entity relationship rules for EclipseLink, Hibernate, and standalone Jakarta/Java Persistence projects without requiring Spring. A shared addendum loader normalizes provider names, deduplicates persistence context, and supplies it to both file analysis and architecture prompts, including incremental dispatch; Spring retains its existing rules plus the shared JPA guidance.

Linked issue(s)

Closes #602.

How I tested this

Eight focused tests check provider aliases, Spring/JPA deduplication, existing framework handling, and the actual helper CLI consuming a scan result. No LLM analysis of a Java application was run.

• pnpm lint
• pnpm --filter @understand-anything/core test — 1,013 passing
• pnpm test — 794 passing, 12 skipped
• pnpm build
• Manual smoke test — provider prompt routing covered by the scan-result CLI regression

Versioning

• Version bumped to 2.9.8 in all six manifests listed in CLAUDE.md
