This pull request adds support for generating GitHub App installation
tokens for enterprise-level installations.
### What changed
- Added a new `enterprise` input to `action.yml`.
- Wired `enterprise` through `main.js` and `lib/main.js`.
- Added validation so `enterprise` cannot be combined with `owner` or
`repositories`.
- Implemented enterprise installation lookup using the direct GitHub API
route `GET /enterprises/{enterprise}/installation`, then used the
returned installation ID to mint an installation token through
`@octokit/auth-app`.
- Updated `README.md` with enterprise installation usage and input
documentation.
- Updated `dist/main.cjs` for the bundled action.
- Shared token creation retry behavior across repository, owner, and
enterprise paths so server errors and transient network errors are
retried, while client errors fail immediately.
### Tests
Added focused test coverage for:
- enterprise token creation
- enterprise token creation with explicit permissions
- enterprise installation not found
- mutual exclusivity with `owner`
- mutual exclusivity with `repositories`
- owner installation client errors are not retried
- transient network errors are retried during token creation
### Notes
- This keeps the existing repository-scoped token behavior unchanged.
- Owner, repository, and enterprise token creation now share the same
retry policy: server errors and recognized transient network errors are
retried, while client errors fail immediately. This intentionally fixes
the previous owner-path behavior that retried client errors.
