docs: add milo to the awesome list

[michaelegbo]

Description of change

Add Milo to the Awesome list's Proprietary section. Milo is a speaking Three.js avatar whose
optional local Node.js edition uses node-llama-cpp for Qwen replies. Its
README credits the runtime, and the
native implementation
loads models and creates chat sessions through node-llama-cpp.

The entry identifies the optional Node.js edition because the hosted browser edition uses
wllama. The source-available badge links to PolyForm Noncommercial 1.0.0; Milo is not presented
as OSI open source.

Validation: npm run build, npm run format, git diff --check, and the conventional PR title
check pass. All three links in the entry return HTTP 200. This change adds one entry only.
The changed page also passes VitePress Markdown rendering and Vue script/template compilation.

The full npm run docs:build did not complete locally on Windows: the default shell rejects
its POSIX NODE_OPTIONS assignment; a rerun through Git Bash was stopped during full-site
generation to keep this documentation-only check bounded. No full-site build success is claimed.
