      summary: Get or stream app logs
      description: Queries or streams runtime logs for an application. A start datetime is required. When an end datetime is omitted, the endpoint streams logs in real time using Server-Sent Events or newline-delimited JSON depending on the Accept header. Supports filtering by revision ID, log level, and full-text search. Cursor-based pagination applies to historical queries.
