URL: https://github.com/apache/tvm/pull/18520
## Why
- Phi-4 uses: partial_rotary_factor = 0.75 (rotary_dim = 96) + longrope
scaling
- Longrope requires: Both long_factors + short_factors packed into one buffer
- Expected buffer size: (rotary_dim,) = (96,) total
- First half [0:48] = long_factors
- Second half [48:96] = short_factors
- llama4_rope_with_position_map still had old size (rotary_dim // 2,) = (48,)
