Permanently delete an artifact from a Polygraph session by name.

This removes the artifact and ALL of its versions, and cannot be undone. Returns the session's remaining artifacts. Use list_artifacts first if you are unsure of the exact name.

## Arguments

| Name | Type | Required | Description |
| ---- | ---- | -------- | ----------- |
| `sessionId` | `string` | yes | The Polygraph session ID, or a supported Polygraph app session URL. Supported URL paths are /s/<session-id> and /orgs/<org-id>/sessions/<session-id>. URL inputs are normalized to the session ID; the MCP always uses the current Polygraph API configuration. |
| `name` | `string` | yes | The name of the artifact to delete. |
