feat: Sentinel postrun scripts

[michaeljguarino]

This can allow users to configure custom cleanup, especially useful if the bring-their-own-tests

Greptile Summary

This PR adds a postrunScript field to the Sentinel integration test configuration, letting users supply a shell script that runs after the test job completes — useful for custom cleanup steps when bringing their own tests.

• New postrun_script field is added end-to-end: Elixir schema/changeset, GraphQL input/output types, Go CRD type, generated client models, and the harness execution path with unit tests.
• runPostrunScript in the sentinel harness executes the script via /bin/sh -c, inheriting the pod environment; when it fails, the job is marked Failed but the failure reason is currently not surfaced in the console job output.

Confidence Score: 3/5

Mostly safe, but a failure in the postrun script will produce a silently failed job with no user-visible explanation.

The postrun script error is consumed and discarded at line 144: the returned output string is unchanged, so the console job output won't mention the postrun failure at all. A user whose cleanup script exits non-zero will see a Failed status with only the test output, with no indication that it was the postrun script.

go/deployment-operator/pkg/sentinel-harness/controller/controller.go — the postrun error handling at lines 143-145

Important Files Changed

Filename	Overview
go/deployment-operator/pkg/sentinel-harness/controller/controller.go	Adds postrun script execution after tests; error handling silently discards the failure reason, leaving users without visibility into why the run failed.
go/deployment-operator/pkg/sentinel-harness/controller/controller_test.go	Adds unit tests for new postrun script functionality and existing JSON decoding helpers; tests cover nil, empty, success, and failure cases.
go/controller/internal/controller/sentinel_controller.go	Passes through the new PostrunScript field from the CRD spec to the console API attributes; straightforward addition with no issues.
go/controller/api/v1alpha1/sentinel_types.go	Adds PostrunScript optional field to SentinelCheckIntegrationTestConfiguration; correctly annotated as optional.
lib/console/schema/sentinel.ex	Adds postrun_script string field to the embedded IntegrationTestConfiguration schema and includes it in the changeset cast; no migration needed (embedded JSON).
lib/console/graphql/deployments/sentinel.ex	Exposes postrun_script on both the input object and the output type; consistent with the schema change.
go/client/models_gen.go	Auto-generated Go client models updated to include PostrunScript on SentinelCheckIntegrationTestConfigurationFragment and attributes struct.
