Pull request overview

This PR adds a discovery-time permission probe to exclude streams that return HTTP 403 from the generated Singer catalog, and updates unit/integration tests and versioning to reflect the new behavior.

Changes:

• Add PardotForbiddenError and raise it on HTTP 403 responses in the client.
• Add discovery-time filtering: check per-stream access, prune child streams when their parent is inaccessible, and fail discovery only if no parent streams are accessible.
• Add/adjust unit tests and update integration-test expectations; bump version and changelog.
