Support loading skills from the.agents directory

[seems20]

What would you like to be added?

As the title suggests, it supports loading skills from the.agents directory.

Why is this needed?

There are many tools that already support loading skills from the.agents directory, including the npx skills add that comes with https://skills.sh/ will also install skills into.agents, which will reduce the configuration cost for users.

@seems20 I noticed that when installing skills using npx skills, skills are only installed to the .agents directory when Antigravity is selected; other coding tools do not support installing skills from this directory.
Alternatively, you can directly select qwen code in the installation options, which will help you install them to the correct location.
