[BUG] /resume picker shows raw <command-name> XML tags as session titles

What's Wrong?

The /resume session picker displays raw internal XML/skill markup as session titles instead of clean names.

Sessions where the first interaction was a slash command (/clear, /rename, /resume) show titles like:

/clear clear

This makes the session list unreadable. Multiple sessions are affected — any session whose first user message was a slash command
shows this raw markup.

What Should Happen?

Session titles should show a clean, human-readable name — either the first actual user message, the renamed title, or a fallback
like the date/time. Internal skill/command XML markup should never leak into the UI.

Error Messages/Logs

No error — purely a display/cosmetic bug in the /resume picker.

Steps to Reproduce

1. Start a new Claude Code session
2. Type /clear as the first command
3. Continue working, then exit the session
4. Run /resume
5. The session list shows the raw markup as the title:

<command-name>/clear</command-name> <command-message>clear</command-message> <command-args></command-args>

1. Same happens for sessions started with /rename or /resume
