Rename a namespace

## Usage

`circleci namespace rename <name> <new-name> [flags]`

## Arguments

- `<name>` is the current name of the namespace, for example, `oldname`.
- `<new-name>` is the new name to assign, for example, `newname`.

## Flags

| Flag          | Description                                                                       |
| ------------- | --------------------------------------------------------------------------------- |
| `--jq string` | Process values from the response using jq syntax (see `circleci help formatting`) |
| `--json`      | Output as JSON                                                                    |

Global flags: `-c, --config`, `--debug`, `--no-color`, `-q, --quiet` — see `circleci --help`.

## Examples

- Rename a namespace: 
  `circleci namespace rename oldname newname`
- Rename and output the result as JSON: 
  `circleci namespace rename oldname newname --json`
- Confirm the new ID after rename: 
  `circleci namespace rename oldname newname --json --jq '.id'`

## Details

Rename a CircleCI orb namespace.

Any orbs already published under the old name will continue to be
accessible — renaming creates an alias. Ensure that any configs
and orbs still referencing the old name are updated.
