api: Move apis package to a separate sub-module (#4362)
- Yaml standalone functions in internal/otelconfig is moved to a methods on *Config (package apis/v1beta1)
- Move CheckTargetAllocatorPrometheusCRPolicyRules from apis/v1beta1/targetallocator_rbac.go to internal/webhook/targetallocator_rbac.go + rename it to checkTargetAllocatorPrometheusCRPolicyRules.
- OpenTelemetryCollector is not implementing the Convertible interface from sigs.k8s.io/controller-runtime/pkg/conversion, but implements 2 helper function the achieve the same functionality:
  - OtelColConvertTo(otc *OpenTelemetryCollector, dstRaw any) error
  - OtelColConvertFrom(otc *OpenTelemetryCollector, srcRaw any) error
- Move apis package to a dedicated sub-module.
target allocator: The operator.targetallocator.mtls feature gate has been removed. mTLS is now configured per-CR via spec.mtls.enabled on the TargetAllocator or Collector resource. (#5136)
Set spec.mtls.useCertManager: false to provide your own TLS secrets instead of having cert-manager provision them.

collector: Add optional spec.command to OpenTelemetryCollector to override the collector container entrypoint (#3188)
spec.command is a []string matching Pod.spec.containers[].command.
target allocator: Add allowInsecureAuthSecrets option to serve auth secret values over plain HTTP without mTLS (#3746)
Adds a new allowInsecureAuthSecrets field to both the TargetAllocator CRD and the
embedded TargetAllocator in the OpenTelemetryCollector CRD. When enabled, auth secret
values (e.g. basicAuth passwords) are served over plain HTTP instead of being masked.
This is useful when transport security is handled by a service mesh or equivalent.

must-gather: Fix must-gather output to produce omc-compatible directory layout and correct YAML serialization (#4965)
Previously collected files used a per-collector directory with kind-prefixed filenames (e.g. namespaces/<ns>/<collector-name>/deployment-<name>.yaml),
which omc cannot parse. Output now follows the standard omc layout (namespaces/<ns>/<api-group>/<resource-plural>/<name>.yaml).
Also fixes missing apiVersion/kind fields in serialized YAML, incorrect default output directory, and adds collection of CRDs and OpAMPBridge resources.
opamp: Skip OpenTelemetryCollector instances with a non-nil DeletionTimestamp when building EffectiveConfig (#5170)
ListInstances returns objects with DeletionTimestamp set until finalizers complete.
Reporting them as effective races with the bridge's own Delete calls in applyRemoteConfig.
collector: Fix Service reconciliation to propagate trafficDistribution, internalTrafficPolicy, ipFamilies, and ipFamilyPolicy changes (#5141)
