Greenfield: Implement direct KRM types, identity, and generate.sh for SaaSServiceMgmtUnit

[neumann-coder-bot]

Description

This PR implements direct KRM types, identity, reference, and generate.sh for the SaaSServiceMgmtUnit greenfield resource (saasservicemgmt.cnrm.cloud.google.com/v1alpha1).

Key Changes

1. Types:
   • Added KRM Go types for SaaSServiceMgmtUnitSpec and SaaSServiceMgmtUnitObservedState in apis/saasservicemgmt/v1alpha1/saasservicemgmtunit_types.go.
   • Included all spec and output-only observed state fields based on the GCP google.cloud.saasplatform.saasservicemgmt.v1beta1.Unit proto.
   • Annotated immutable fields (location, unitKind, tenant, managementMode) with CEL rules.
2. Identity & Reference:
   • Implemented SaaSServiceMgmtUnitIdentity adhering to identity.IdentityV2 and identity.Resource interfaces in apis/saasservicemgmt/v1alpha1/saasservicemgmtunit_identity.go.
   • Implemented SaaSServiceMgmtUnitRef adhering to refs.Ref using refs.Normalize in apis/saasservicemgmt/v1alpha1/saasservicemgmtunit_reference.go.
   • Added unit tests in apis/saasservicemgmt/v1alpha1/saasservicemgmtunit_identity_test.go.
3. Scaffolding & Mapper:
   • Updated apis/saasservicemgmt/generate.sh to include --resource SaaSServiceMgmtUnit:Unit.
   • Generated CRD manifest, deepcopy functions, and proto-to-KRM mappers.

Investigating unit-tests-2-of-4 failure

Run: 36947566188
Name: unit-tests-2-of-4
Cause: Test Failure
Details: The newly added SaaSServiceMgmtUnit alpha CRD introduced fields that are not yet covered by test fixtures (which are created in Phase 2). The missing field ratchet check TestCRDFieldPresenceInTestsForAlpha in tests/apichecks failed because tests/apichecks/testdata/exceptions/alpha-missingfields.txt needed to be updated with the newly added CRD's missing fields.
Action Taken: Updated tests/apichecks/testdata/exceptions/alpha-missingfields.txt to include SaaSServiceMgmtUnit missing field exceptions, verified all tests/apichecks and apis/saasservicemgmt unit tests pass cleanly, validated generated files, and pushed the updated commit.

KCC Auto-Review Results

• Trigger criteria matched: Yes
• API Version Check: Pass - (CRD and Go types correctly placed under apis/saasservicemgmt/v1alpha1/ as v1alpha1)
• Go Type Pointers: Pass - (All Go scalar primitive fields including Location use pointers; collection types are non-pointer slices)
• Completeness & Heuristics: Pass - (All fields from google.cloud.saasplatform.saasservicemgmt.v1beta1.Unit are 100% accounted for, with output-only fields properly mapped to ObservedState)
• 1:1 Kind to Proto Mapping: Pass - (1:1 relationship between SaaSServiceMgmtUnit and Unit proto)
• References/Identity: Pass - (Implemented IdentityV2 and refs.Ref using refs.Normalize and gcpurls.Template)
• Exception Files: Pass - (Only updated tests/apichecks/testdata/exceptions/alpha-missingfields.txt)

Detailed Findings / Actions Required:
