new feature: Add delete options support for Go binding

### Feature Description Add DeleteOptions support to the Go binding's Delete operation. Currently, the Go binding only exposes: ``` func (op *Operator) Delete(path string) error ``` The Rust core supports two additional options via `DeleteOptions`: * version — delete a specific version of an object (useful for versioned storage backends such as S3 versioning, GCS object versioning) * recursive — recursively delete all objects under a given path prefix The Go binding should expose an equivalent `DeleteWith` function (or functional options pattern consistent with the existing `List` options style) to support these options. ### Problem and Solution Users of the Go binding who work with versioned storage backends (e.g. S3 with versioning enabled) cannot delete a specific version of an object. They also cannot perform a recursive delete without manually listing and deleting each object, which is error-prone and inefficient. The Rust core already supports both capabilities via `DeleteOptions`: ``` // core/src/types/operator/operator_futures.rs pub struct DeleteOptions { pub version: Option<String>, pub recursive: bool, } ``` Solution: Implement `DeleteWith` in the Go binding using the same functional options pattern already used by `ListWith`: ``` // Option types type DeleteOption func(*deleteOptions) type deleteOptions struct { version string recursive bool } func DeleteWithVersion(version string) DeleteOption { return func(o *deleteOptions) { o.version = version } } func DeleteWithRecursive() DeleteOption { return func(o *deleteOptions) { o.recursive = true } } // New method on Operator func (op *Operator) DeleteWith(path string, opts ...DeleteOption) error ``` ### Additional Context _No response_ ### Are you willing to contribute to the development of this feature? - [x] Yes, I am willing to contribute to the development of this feature.
