feat(ai): switch default model to qwen2.5-coder:7b + nomic-embed-text

Replaces deepseek-coder-v2:lite (too large for 8GB target) with
qwen2.5-coder:7b (4.7GB GGUF, ~5.5GB runtime, Apache 2.0, best-in-class
DevOps/container/SELinux coding benchmark). Adds nomic-embed-text (274MB)
as the embedded vector model. Updates env.defaults, profile.toml, and the
OpenAI-compatible models catalog. Also adds Windows 11 one-liner install
entry to README.md.
