* source/gateway-api: Migrate Gateway and HTTPRoute from v1beta1 to v1
This migrates the Kubernetes API interactions for Gateway and HTTPRoute
objects from v1beta1 to v1.
The v1beta1 revert was originally made in PR #4610 (July 2024) because
GKE clusters were not yet serving v1 CRDs. That is no longer the case:
v1 Gateway and HTTPRoute have been available since Gateway API v1.0.0
(October 2023) and all major managed Kubernetes providers now serve them.
This change does NOT modify TLSRoute, TCPRoute, or UDPRoute, which
remain at v1alpha2. TLSRoute's migration to v1 depends on Gateway API
v1.5.0+ and is tracked separately in #6247.
* Updated Gateway API "Supported API Versions" section.
* Document minimum supported Gateway API CRD version

* feat(annotations): add custom annotation prefix support for split horizon DNS
Add --annotation-prefix flag to allow customizing the annotation prefix
used by external-dns. This enables split horizon DNS scenarios where
multiple instances process different sets of annotations from the same
Kubernetes resources.
Changes:
- Add AnnotationPrefix field to Config with validation
- Convert annotation constants to variables that can be reconfigured
- Add SetAnnotationPrefix() function to rebuild annotation keys
- Integrate annotation prefix setting in controller startup
- Update Helm chart with annotationPrefix value
- Add comprehensive split horizon DNS documentation
- Update FAQ with annotation prefix examples
This maintains full backward compatibility - the default prefix remains
"external-dns.alpha.kubernetes.io/".

* refactor(annotations): remove init() for explicit initialization
- Remove init() function from annotations package
- Add explicit SetAnnotationPrefix() call in controller/execute.go
- Remove annotation key aliases from source/source.go
- Replace all alias usages with annotations.* references (348 changes in 28 files)
- Add TestMain to existing test files (service_test.go, cloudflare_test.go)
This change makes annotation initialization explicit and predictable,
avoiding hidden global state initialization at import time.

* refactor(annotations): replace hardcoded annotation prefix with constant
Replace all hardcoded "external-dns.alpha.kubernetes.io/" strings
with annotations.DefaultAnnotationPrefix constant to establish
a single source of truth.
Changes:
- Add DefaultAnnotationPrefix constant in source/annotations/annotations.go
- Replace hardcoded string in controller/execute.go with constant reference
- Replace hardcoded strings in pkg/apis/externaldns/types.go (2 occurrences)
- Add helm unit tests for annotationPrefix value
This eliminates string duplication and makes future changes easier.

This code referenced the endpoints variable which was updated with each
resource leading to confusing debug messages - this sets up a new array
each iteration to log just the records from the relevant Gateway resource.
