Directory entry name mismatch: "co2-tracker" should be "claude-carbon"

**Summary**

My plugin was submitted via the official submission form and shows as **claude-carbon — Published (Aug 1)** in the Console at platform.claude.com/plugins/submissions. However, the community directory entry in `.claude-plugin/marketplace.json` lists it under a different name:

```json
{
"name": "co2-tracker",
"source": {
"source": "url",
"url": "https://github.com/gwittebolle/claude-carbon.git"
},
"homepage": "https://github.com/gwittebolle/claude-carbon"
}
```

The plugin's own manifest (`.claude-plugin/plugin.json` in the repo) declares `"name": "claude-carbon"`, and every other distribution channel uses that name: the GitHub repo, the npm package (`npx claude-carbon`), the docs and the install instructions published everywhere.

**Impact**

Users who look for "claude-carbon" in the community marketplace can't find it, and `claude plugin install co2-tracker@claude-community` diverges from all documented install paths.

**Request**

Please rename the directory entry from `co2-tracker` to `claude-carbon` so it matches the submission and the plugin manifest. The entry was published on Aug 1 with a small install base so far, so renaming now would cause minimal breakage compared to later.

I first reported this on Aug 4 but haven't heard back, hence this issue. Happy to provide anything needed on my side.

Open .claude-plugin/marketplace.json and locate the entry whose URL points to gwittebolle/claude-carbon.git. Compare its name with .claude-plugin/plugin.json and the documented install name, then rename only the directory entry to claude-carbon and verify that no marketplace references still use co2-tracker.
