Dragonfly client can't download any images due to ?ns=docker.io param

[Marnhiar]

Bug report:

When downloading images from docker.io dragonfly client is adding ?ns=docker.io param to the url and causing it to receive 400 Bad Request.

Expected behavior:

Pulling new nginx image should work without problem and become seeded. ns param should be filtered by this fix from client v1.1.17. dragonflyoss/client#1580

How to reproduce it:

Containerd: v2.2.1
Kubernetes: v1.35.0
Values:

global:
  storageClass: "freenas-iscsi-csi"

manager:
  image:
    repository: dragonflyoss/manager
    tag: v2.4.1
  metrics:
    enable: true

scheduler:
  image:
    repository: dragonflyoss/scheduler
    tag: v2.4.1
  metrics:
    enable: true

seedClient:
  image:
    repository: dragonflyoss/client
    tag: v1.2.10
  metrics:
    enable: true

mysql:
  primary:
    startupProbe:
      failureThreshold: 30
      periodSeconds: 10

client:
  image:
    repository: dragonflyoss/client
    tag: v1.2.10
  metrics:
    enable: true
  dfinit:
    enable: true
    image:
      repository: dragonflyoss/dfinit
      tag: latest
    config:
      containerRuntime:
        containerd:
          configPath: /etc/containerd/config.toml
          registries:
            - hostNamespace: docker.io
              serverAddr: https://index.docker.io
              capabilities: ['pull', 'resolve']

Environment:

• Dragonfly version: v2.4.1 Client: v1.2.10
• OS: Ubuntu 24.04.3 LTS
• Kernel (e.g. uname -a): 6.8.0-94-generic x86_64

@Marnhiar Why does add the 'ns' parameter cause a 400 error in the response? Dragonfly didn't add the query parameters. containerd added the 'ns' query parameter."

Shouldn't dragonfly client filter 'ns' query parameter out when pulling the image blobs? My understanding might be wrong since it's my first time trying dragonfly. There wasn't any other people that was encountering same issue. My configuration seems correct according to the document
