Function registerS3BucketTools

registerS3BucketTools(
    server: ToolRegistrar,
    s3: Pick<
        B2S3PeerClient,
        "headBucket"
        | "putBucketLifecycle"
        | "deleteBucketLifecycle",
    >,
    config: B2Config,
): void
Register S3-compatible bucket reachability and lifecycle tools.
Parameters
- server: ToolRegistrar
  Tool registrar receiving S3 bucket tools.
- s3: Pick<
      B2S3PeerClient,
      "headBucket"
      | "putBucketLifecycle"
      | "deleteBucketLifecycle",
  >
  Repository-owned S3-compatible client facade.
- config: B2Config
  Server configuration used for destructive policy.
Returns void
Remarks
These retained S3 tools cover features that either validate S3 endpoint reachability or lack a native B2 equivalent. Lifecycle expiration and empty-rule clearing are routed through the shared destructive gate.
Example
```
registerS3BucketTools(registrar, s3Client, config);
```
