List an org's organization roles

Use list_organization_roles to see every predefined and custom organization role an org has defined, before looking up who holds any of them.

Prerequisites

github-org-identity installed.
A GitHub token (GITHUB_TOKEN env var, or gh auth token fallback) whose identity holds the org’s admin:org scope (classic PAT) or an App-installation token with the org-level members/ organization_administration permission. This is a read call, but the organization-roles endpoint requires the same scope for reads as writes.

Ask for the tool with the org’s login:

Use list_organization_roles for org my-org.
Read the result — an array of:
```
{ "id": 8132, "name": "all_repo_read", "description": "View all repositories", "source": "Predefined", "baseRole": null }
```
source distinguishes GitHub’s predefined roles from ones the org defined itself (Organization). baseRole is set only when a custom role was built on top of a predefined base.
Note the id of any role you want to inspect further — it’s the roleId every other tool in this plugin takes, not the role’s name.

missing_scope — no resolvable token. Set GITHUB_TOKEN, or run gh auth login --scopes admin:org.
github_api_error with a 403/404 — the resolved identity doesn’t have org-roles read access, or the org login is wrong.
