Pull request overview

This PR updates discovery to exclude streams the provided RingCentral credentials cannot read (HTTP 403), so the generated Singer catalog contains only accessible streams.

Changes:

• Add stream-level access probing during discovery (and prune child streams when a parent is inaccessible).
• Treat HTTP 403 as a non-retryable permission error via a new RingCentralForbiddenError.
• Update unit tests and bump version/changelog for the new behavior.
