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

ファイルやテストは指定されていません。まず cmdc taste のエントリポイントと Studio Taste タブをたどり、次に list --remote がパッケージを読み込む方法と、パッケージカードまたは詳細ビューがどのようにレンダリングされるかを追ってください。認証済みユーザーが選択したリモートパッケージを両方の経路から削除でき、パッケージがリモートの一覧から削除されれば完了です。
