Summary
This PR fixes a runtime error when loading Qwen3 models with newer versions of transformers(>5).
Problem
Qwen3Attention forwards config.rope_scaling into get_rope(...), but get_rope() does not currently implement RoPE scaling and assumes rope_scaling is None.
In newer transformers versions, config.rope_scaling may be parsed as a dict, which causes:
TypeError: unhashable type: 'dict'
because get_rope() is cached with lru_cache.
Fix
Pass rope_scaling=None explicitly in Qwen3Attention.
This keeps behavior aligned with the current implementation status and avoids the runtime error without changing existing RoPE logic.
Fixes #189
