Introduces internal/apistatus, a leaf package that gives provider implementations a structured way to return non-retryable errors to controllers without coupling directly to reconcile.TerminalError. The package defines a Code enum (CodeInvalidArgument, CodeUnsupportedField, CodeFailedPrecondition) with String() and Valid() methods, a StatusError struct carrying a Code, an optional Message, and optional FieldViolations, and constructor functions for each code. StatusError implements Is() so that errors.Is can be used for type detection across error chains. WrapTerminalError wraps any error containing a *StatusError as a reconcile.TerminalError, leaving all other errors unchanged. conditions.FromError is extended to detect *StatusError before the existing gRPC status path, mapping the code to the condition Reason and the formatted message to the condition Message field. The stub internal/controllerutil package, which this supersedes, has been removed as no code imported it. Signed-off-by: Felix Kästner <felix.kaestner@sap.com>
Each controller's Reconcile method now passes provider errors through apistatus.WrapTerminalError before returning them to controller-runtime. This ensures that any *StatusError returned by a provider implementation — signalling an unsupported field, an invalid argument, or an unmet precondition — suppresses retry backoff and is treated as a terminal error by the reconciler. Transient errors and Kubernetes-level precondition failures are returned unchanged, preserving existing retry behaviour for those cases. Signed-off-by: Felix Kästner <felix.kaestner@sap.com>
Replace plain fmt.Errorf/errors.New calls in the NX-OS provider and name.go with typed apistatus errors so non-retryable failures surface as structured Kubernetes status conditions with a stable Reason field. Signed-off-by: Felix Kästner <felix.kaestner@sap.com>
WrapTerminalError now only promotes CodeInvalidArgument and CodeUnsupportedField to reconcile.TerminalError. CodeFailedPrecondition errors pass through unchanged so controller-runtime exponential backoff can requeue them — the precondition (e.g. a BGP process) may become true on a future attempt. Update docs and tests to reflect the new behaviour. Signed-off-by: Felix Kästner <felix.kaestner@sap.com>

Merging this branch changes the coverage (3 decrease, 1 increase)
Coverage by fileChanged files (no unit tests)
Please note that the "Total", "Covered", and "Missed" counts above refer to code statements instead of lines of code. The value in brackets refers to the test coverage of that file in the old version of the code. Changed unit test files

Happy to use this package also for IOS XR. Thanks for that :).
