fix(acp): update Claude ACP adapter to @agentclientprotocol scope (#447)

## Summary
🤖 Generated with [Nori](https://www.npmjs.com/package/nori-ai)

- Update Claude ACP adapter npm package from deprecated
`@zed-industries/claude-agent-acp` (frozen at 0.23.1) to
`@agentclientprotocol/claude-agent-acp` (active, latest 0.30.0)
- Codex adapter (`@zed-industries/codex-acp`) is unchanged — it has not
been renamed or deprecated

## Test Plan
- [x] `test_get_claude_code_config` verifies the built-in Claude config
uses the new package name
- [x] All 16 ACP crate tests pass
- [x] Clippy clean
