* 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.

In order to filter annotations in informer transformers, this PR makes it more explicit that a common prefix is used.
New prefixes can be added later-on if need be, but all annotations should be anchored in a known prefix.
