Breaking Changes

Metrics::new and Metrics::new_registered now require a namespace parameter.

The koprs_ prefix has been removed from the hard-coded metric names. Both constructors
now accept a namespace: &str argument that is prepended to every metric name with an
underscore separator.

Before	After
Metrics::new()	Metrics::new("myoperator")
Metrics::new_registered(&registry)	Metrics::new_registered("myoperator", &registry)
metric: koprs_reconciliations_total	metric: myoperator_reconciliations_total
metric: koprs_reconcile_errors_total	metric: myoperator_reconcile_errors_total
metric: koprs_reconcile_duration_seconds	metric: myoperator_reconcile_duration_seconds

Pass "" for no prefix (bare names like reconciliations_total).

Metrics::default() is unchanged and now resolves to Metrics::new("").

ControllerBuilder::metrics_port internally passes "", so operators using the builder
API with no direct Metrics construction are not affected by the API signature change,
but their published metric names will change from koprs_* to the bare names above.
Update any Prometheus alert rules or dashboards accordingly.
