a9c2c0de89 fix(style): migrate from deprecated github.com/pkg/errors package (#1071)
* refactor: migrate error packages from pkg/errors to stdlib

Replace github.com/pkg/errors with Go standard library error handling
in foundation error packages:

- internal/datastore/errors: errors.Wrap -> fmt.Errorf with %w
- internal/errors: errors.As -> stdlib errors.As
- controllers/soot/controllers/errors: errors.New -> stdlib errors.New

Part 1 of 4 in the pkg/errors migration.

* refactor: migrate datastore package from pkg/errors to stdlib

Replace github.com/pkg/errors with Go standard library error handling
in the datastore layer:

- connection.go: errors.Wrap -> fmt.Errorf with %w
- datastore.go: errors.Wrap -> fmt.Errorf with %w
- etcd.go: goerrors alias removed, use stdlib errors.As
- nats.go: errors.Wrap/Is/New -> stdlib equivalents
- postgresql.go: goerrors.Wrap -> fmt.Errorf with %w

* chore: run go mod tidy after pkg/errors migration

The github.com/pkg/errors package moved from direct to indirect
dependency. It remains as an indirect dependency because other
packages in the dependency tree still use it.

* fix(datastore): use errors.Is for sentinel error comparison

The stdlib errors.As expects a pointer to a concrete error type, not
a pointer to an error value. For comparing against sentinel errors
like rpctypes.ErrGRPCUserNotFound, errors.Is should be used instead.

* fix: resolve golangci-lint errors

- Fix GCI import formatting (remove extra blank lines between groups)
- Use errors.Is instead of errors.As for mutex sentinel errors

* fix(errors): use proper variable declarations for errors.As

The errors.As function requires a pointer to an assignable variable,
not a pointer to a composite literal. The previous pattern
`errors.As(err, &SomeError{})` creates a pointer to a temporary value
which errors.As cannot reliably use for assignment.

This fix declares proper variables for each error type and passes
their addresses to errors.As, ensuring correct error chain matching.

* fix(datastore/etcd): use rpctypes.Error() for gRPC error comparison

The etcd gRPC status errors (ErrGRPCUserNotFound, ErrGRPCRoleNotFound)
cannot be compared directly using errors.Is() because they are wrapped
in gRPC status errors during transmission.

The etcd rpctypes package provides:
- ErrGRPC* constants: server-side gRPC status errors
- Err* constants (without GRPC prefix): client-side comparable errors
- Error() function: converts gRPC errors to comparable EtcdError values

The correct pattern is to use rpctypes.Error(err) to normalize the
received error, then compare against client-side error constants
like rpctypes.ErrUserNotFound.

b40428825d feat: add ObservedGeneration (#1069)
* feat: add ObservedGeneration to all status types

Add ObservedGeneration field to DataStoreStatus, KubeconfigGeneratorStatus,
and TenantControlPlaneStatus to track which generation the controller has
processed. This enables clients and tools like kstatus to determine if the
controller has reconciled the latest spec changes.

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

* refactor: follow Cluster API pattern for ObservedGeneration

Move ObservedGeneration setting for TenantControlPlane from intermediate
status updates to the final successful reconciliation completion. This
follows Cluster API conventions where ObservedGeneration indicates the
controller has fully processed the given generation.

Previously, ObservedGeneration was set on every status update during
resource processing, which could mislead clients into thinking the spec
was fully reconciled when the controller was still mid-reconciliation
or had hit a transient error.

Now:
- DataStore: Sets ObservedGeneration before single status update (simple controller)
- KubeconfigGenerator: Sets ObservedGeneration before single status update (simple controller)
- TenantControlPlane: Sets ObservedGeneration only after ALL resources processed successfully

* test: verify ObservedGeneration equals Generation after reconciliation

Add assertion to e2e test to verify that status.observedGeneration
equals metadata.generation after a TenantControlPlane is successfully
reconciled.

* chore: regenerate CRDs with ObservedGeneration field

Run make crds to regenerate CRDs with the new ObservedGeneration
field in status types.

* Run make manifests

* Run make apidoc

* Remove rbac role

* Remove webhook manifest
