* 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/".

* docs(advanced): fix markdown formatting in split-horizon guide

* 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.

✨ Add support for ExternalIPs in Istio Gateway and VirtualService
ℹ️ This commit extends Istio Gateway and VirtualService resources
to support ExternalIPs. The changes include:
- Checking if service has ExternalIPs defined
- If yes, adding them to the list of targets
- If not, continuing with the existing process
👌 Now you can have your Istio resources use `externalIPs` too! 🎉
Not to be `ip`-percritical, but don't we all love an `ip`grade! 🎈
