Wire QwenNetworkLoader into CLI for proper Qwen3 inference

[michalharakal]

Context

The CLI (Main.kt) always routes GGUF models through LlamaIngestion → LlamaRuntime, which works for Llama-architecture models. Qwen3 models load successfully (same tensor names), but produce garbage output because LlamaRuntime doesn't handle Qwen3-specific features:

• QK-norm (query/key normalization via attn_q_norm.weight / attn_k_norm.weight)
• RoPE base frequency (1,000,000 vs Llama's 10,000)
• BOS token differences

The correct loader (QwenNetworkLoader in llm-inference:qwen) exists but isn't wired into the CLI.

Scope

• Add :llm-inference:qwen dependency to :llm-runtime:kllama
• Detect qwen* architecture from GGUF metadata in Main.kt
• Route to QwenNetworkLoader.fromGguf() for Qwen models
• Wire the Qwen DSL network module into a runtime compatible with AgentLoop
• Validate end-to-end with Qwen3-1.7B-Q8_0.gguf --demo

• Depends on architecture detection added in Generalize tool-calling support across model families #35 commits

Acceptance Criteria

• Qwen3-1.7B-Q8_0.gguf --demo produces coherent output
• Tool calling works through the Qwen chat template
• Llama models continue working unchanged
