Feature request: Improve chat naming when using custom skills

Summary

When invoking custom skills (e.g., /newfeature), the VSCode extension names the chat using the internal XML representation <command-message>newfeature</command-message> instead of a human-readable format.

Current Behavior

After creating a custom skill and using it multiple times, the chat history shows entries like:

• <command-message>newfeature</command-message>
• <command-message>newfeature</command-message>
• <command-message>newfeature</command-message>

This makes it impossible to distinguish between different chats when searching or browsing history.

Expected Behavior

The chat should be named using a more descriptive format, such as:

• newfeature: email-reengagement (skill name + first argument)
• New Feature: email-reengagement (formatted skill name + argument)
• Or simply use the first user message content after skill expansion

Environment

• Claude Code VSCode Extension
• Windows 11
• Custom skills defined in .claude/skills/

Suggested Improvement

When a skill is invoked, extract the skill name and arguments to create a readable chat title instead of using the internal command representation.
