chore(main): release 3.2.0

feat: add support for enterprise-level GitHub Apps (#263 )
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.

The documentation also lists all available permissions, just prefix the permission key with `permission-` (e.g., `pull-requests` → `permission-pull-requests`).

-1. The token is scoped to the current repository or `repositories` if set.
-2. The token inherits all the installation's permissions.
-3. The token is set as output `token` which can be used in subsequent steps.
-4. Unless the `skip-token-revoke` input is set to true, the token is revoked in the `post` step of the action, which means it cannot be passed to another job.
-5. The token is masked, it cannot be logged accidentally.
+The token target depends on the inputs: `enterprise` creates a token for an enterprise installation, `owner` without `repositories` creates a token for all repositories in the owner's installation, `repositories` scopes the token to those repositories, and no target inputs scopes the token to the current repository.
