Allow deleting remote Taste packages from web (Studio) and CLI

Feature Description

Holas.
There is currently no way to delete remote Taste packages (commandcode.ai/username/taste). I verified
this in two places:

1. Web / Studio: The Taste tab in commandcode.ai/studio only lets you view, push, and pull profiles.
   Opening a remote package shows no "Delete", "Remove", or trash icon to delete it. The public view
   (/username/taste) is read-only.
2. CLI: cmdc taste (equivalent to npx taste) only exposes push, pull, list, lint, open. There is no
   delete/rm subcommand or flag to remove a remote package.

Request: Add the ability to delete remote Taste packages in both channels:

• In Studio: a delete button per package (on the package card and/or in the detail view).
• In CLI: a subcommand like cmdc taste delete --remote (or rm) that removes the package from
  the remote registry.

Use Case

I have 2 old remote packages (waku-portafolio, michi-cards-final) and want to reduce them to
a single one (my global Taste). Today the only option is to overwrite with push --overwrite; I cannot
delete the remote I no longer use. This accumulates obsolete profiles and prevents keeping a single
clean remote.

Additional Context

Expected behavior:

• In Command Code Studio (commandcode.ai/studio → Taste tab), each remote Taste package should have
  a delete/remove control (trash icon or "Delete" button) both on the package card and inside the
  package detail view, allowing the user to permanently remove a remote package.
  • The CLI should provide a delete subcommand, e.g. cmdc taste delete --remote (or rm),
    that removes a package from the remote registry (commandcode.ai/username/taste).
  • A user should be able to reduce their remote Taste packages to a single one (e.g. their global
    Taste) by deleting the obsolete ones.

Actual behavior:

• Studio's Taste tab only supports viewing, pushing, and pulling profiles. Opening a remote package
  shows no delete/remove option — the public view (/username/taste) is read-only.
  • cmdc taste --help lists only push, pull, list, lint, open. There is no delete/rm subcommand or
    flag to remove a remote package.
  • cmdc taste list --remote lists remote packages but offers no way to delete them.
  • The only available action is cmdc taste push --all --remote --overwrite, which overwrites an
    existing package but cannot remove a remote package the user no longer wants (e.g. old
    waku-portafolio and michi-cards-final packages remain in the registry with no deletion path).

Steps to reproduce:

1. cmdc taste list --remote → lists remote packages with no delete option.
2. cmdc taste --help → no delete command listed.
3. Studio → Taste → open a package → no delete option.

Important for my workflow

Không có tệp hoặc bài kiểm thử nào được nêu tên. Hãy bắt đầu bằng cách lần theo điểm vào cmdc taste và tab Studio Taste, sau đó theo dõi cách list --remote đọc các package và cách các thẻ package hoặc chế độ xem chi tiết được render. Công việc được hoàn thành khi người dùng đã xác thực có thể xóa một package remote đã chọn thông qua cả hai kênh, với package đó được xóa khỏi các danh sách remote.
