Add skill management and import cloud skill features to the plugin UI

[AfterStories]

I’ve noticed a new PR that adds a command to the CLI for importing skills from a URL,

#11113

but this functionality hasn’t been implemented in the plugin yet.

Many popular agent store platforms now offer various MCP or agent skill packages for users to download.

Is it possible to add an Agent skills management page to the plugin’s UI? This page could display a list of currently available local skills, allowing users to enable or disable them, as well as create or delete them.

It would also be useful to configure a URL in this skills configuration page so we can request and download skill files from the web to user local
Cursor already has a similar page in its settings window. I think maybe we can learn about some detail from it
