Add WorkGround2 — local-first AI engineering workbench

[KiddPhenix]

What

Adds WorkGround2 to the Open Source CLI coding agents section.

WorkGround2 is a local-first AI engineering workbench — one Go agent kernel behind four entry points:

• CLI/TUI (workground2) — terminal-native session
• serve — HTTP/SSE web frontend
• Wails desktop app — completion widget + summaries, no screen-watching
• IM bots (Feishu / WeCom / QQ) — relay tasks to a local session

It reads/writes code and runs commands autonomously under a single control chain: multi-model providers (DeepSeek / OpenAI-compatible / Anthropic / local CLI), MCP + plugins (stdio / Streamable HTTP / SSE), project memory (AGENTS.md / WorkGround2.md / auto memory index), and safe execution (permission policy, sandbox, approval, checkpoints + /rewind).

• Language: Go
• Stars: 1 (early)

Why it fits

Meets the inclusion requirements: has a CLI/terminal interface, can read/write code and run commands autonomously, and the repo is active. Placed after Ferrum (⭐2) per star ordering.

Happy to adjust wording or move sections if it fits better elsewhere.
