Support for SSD expert streaming is not being detected correctly. #112

Description

@patrick-sunderland

print("[SwiftLM] ⚠️ Model does not support SSD expert streaming (\(profile.modelType) is not MoE). Ignoring --stream-experts flag.")

It seems this gets (wrongly) triggered when running with:
--model Qwen/Qwen3.5-397B-A17B (or an 8-bit MXFP8 quantized version thereof) --stream-experts
Resulting in:

"Model does not support SSD expert streaming (qwen3_5_moe is not MoE). Ignoring --stream-experts flag."

Along with a subsequent:

"zsh: killed ./SwiftLM....." 

Running with the same --model and ./SwiftLM parameters works fine when using the latest release binary (SwiftLM b648).

Example:

./SwiftLM \
  --model "/Users/user/models/Qwen3.5-397B-A17B-mxfp8-grp32" \
  --port 5413 --stream-experts --thinking --ssd-prefetch
