Customer.io skill claims the generic `cli` name

`cio skills install` currently installs the Customer.io skill at `~/.agents/skills/cli`. That generic name collides with unrelated CLI work - in my case, a ChartMogul CLI request loaded the Customer.io instructions.

Confirmed on `cio` 0.0.20:

```console
$ cio skills install --global --target codex --dry-run --refresh
"skill":"cli"
```

The checked-in skill already uses `cio`. Could the hosted skill use that name too?

Start by running the reported `cio skills install --global --target codex --dry-run --refresh` command on version 0.0.20 and compare the hosted skill name with the checked-in `cio` name. Trace where the hosted skill metadata is defined or published; done means the dry-run and installed path use `cio` instead of the generic `cli`, without the collision described.
