chore(llm): update llama-cpp, llama-swap and switch to qwen3.5-27b-thinking

- Bump llama-cpp from version 8157 to 8196
- Bump llama-swap from version 192 to 197
- Switch default assistant model from qwen3-coder-next-80b to qwen3.5-27b-thinking
- Remove glm-4-32b-instruct model configuration
- Update qwen3.5-27b-thinking config:
  - Use bartowski quantization (IQ4_XS) instead of unsloth
  - Increase context window from 131k to 196k
  - Add cache type settings (q8_0) and CUDA device
- Add 1password-cli to home-manager programs
- Fix typo: 'dispay' -> 'display' in llm-config.lua
