v1.2.0 — Add GLM, Spark, ERNIE providers

Add three new Chinese LLM providers with OAuth PKCE sign-in:

• GLM (Zhipu AI) — OAuth PKCE via open.bigmodel.cn, access token for chat completions API
• Spark (iFlytek) — OAuth PKCE via spark-api.xf-yun.com, OpenAI-compatible chat completions
• ERNIE (Baidu) — OAuth PKCE via openapi.baidu.com, access token as URL param for WenxinWorkshop API

All three use env-driven credentials (GLM_CLIENT_ID/SECRET, SPARK_CLIENT_ID/SECRET, ERNIE_CLIENT_ID/SECRET).

v1.1.3 — README cleanup and topic expansion

Documentation improvements: cleaned READMEs, removed control characters, expanded topic tags (deepseek-harness, oauth, llm-provider, claude, codex, grok, openrouter, agnes-ai), improved provider table and tool documentation.

v1.1.2 - Add Antigravity, OpenRouter & Agnes AI

What's New

New Providers

• OpenRouter — OAuth PKCE → API key (any provider model)
• Agnes AI — OAuth PKCE → access token (reverse-engineered from AgnesCode)
