Adds support new way to define an entrypoint for Python cron services. With this it would be possible to define a cron service as follows:

{
  "experimentalServices": {
    "cleanup": {
      "type": "cron",
      "entrypoint": "jobs.cleanup:run_cleanup",
      "schedule": "0 0 * * *"
    }
  }
}

Note

Low Risk Change

This PR adds a new optional configuration field and parsing logic for Python cron service entrypoints, representing a feature addition with no security-sensitive changes, auth modifications, or schema/migration impacts.

  • Adds optional handlerFunction field to Service type for cron module:callable entrypoints
  • New regex-based parsing for Python module:attr entrypoint format in fs-detectors
  • Extensive test coverage added for new entrypoint resolution and validation

Risk assessment for commit 87f4f0c.
