[BUG] `matcher: "Skill"` no longer works for hooks

Preflight Checklist

• [x] I have searched existing issues and this hasn't been reported yet
• [x] This is a single bug report (please file separate reports for different bugs)
• [x] I am using the latest version of Claude Code

What's Wrong?

Claude used to support matching on skill load as part of PreToolUse hooks (was working as of 2.1.59). However this seems to have been removed from documentation as well as no longer firing. There appears to be no replacement

What Should Happen?

Skill loading should fire tool use hooks. Or at least there should be a replacement to this breaking change

Steps to Reproduce

Create a hook

"PostToolUse": [
      {
        "matcher": "Skill",
        "hooks": [
          {
            "type": "command",
            "command": "touch /tmp/loaded",
          }
        ]
      }
    ]

Load any skill in claude and notice that nothing happens.
