Yufeng He 0d836afd34 fix: keep max pagerank for repeated n-hop edges (#15696) ...

## Summary

Fixes #15695.

The Python GraphRAG path already accumulates similarity when several
N-hop paths produce the same edge, but PageRank was overwritten by the
last path. That makes ranking depend on path order for repeated edges.

This keeps the strongest PageRank seen for a repeated edge in the Python
implementation:

- `rag/graphrag/search.py`

The similarity score still accumulates exactly as before.

## To verify

- `python -m py_compile rag\graphrag\search.py`
- `git diff --check`
- `git diff --stat upstream/main` -> only `rag/graphrag/search.py`

I originally included the Go implementation too, but removed it after
maintainer feedback because the Go version is still under development
and not released yet.
