Add ccg-router to Model Providers & Proxies

[linny006]

Adds ccg-router under the Model Providers & Proxies section.

It's a local Go daemon that serves OpenAI-compatible /v1/chat/completions (for Codex CLI) and Anthropic-compatible /v1/messages (for Claude Code) on one port, so both CLIs can share one routing config and one local SQLite usage ledger. Apache-2.0, single static binary.

Why I think it fits this list:

• Direct Codex CLI integration via OPENAI_BASE_URL=http://127.0.0.1:17180.
• Sits in the same lane as existing entries like router-for-me/CLIProxyAPI, lich0821/ccNexus, and icebear0828/codex-proxy, but with an explicit dual-CLI focus and a per-request local ledger.
• Actively maintained (released this month, repo public and accepting issues).

Format follows the section's existing convention (entry name, dash separator, value-led description, shields.io stars badge).

Checked:

• Entry placed in the most appropriate section.
• Description is one sentence describing value, not promo copy.
• Star badge included.
• Direct Codex CLI relevance.
• No duplicate entry already in the list.

Quick update: just shipped v0.2.0 with streaming passthrough for both protocols (released today, https://github.com/XZXY-AI/ccg-router/releases/tag/v0.2.0). The "v0.1 = non-streaming" caveat in the entry text is no longer accurate — happy to edit the PR if helpful, or leave as-is since the entry description doesn't mention streaming.
