[BUG] /resume session picker shows raw XML tags instead of readable session titles

What's Wrong?

The /resume session picker displays raw XML metadata tags instead of parsed, human-readable session titles. Each session entry shows:

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

Instead of a readable summary like "clear" or the actual conversation topic.

This happens for all sessions in the list, making it very difficult to identify which session to resume.

What Should Happen?

The resume picker should display parsed, human-readable session titles/summaries — not raw XML metadata tags.

2. Run claude and type /resume (or run claude --resume from terminal)
3. Observe that session titles display raw <command-name>, <command-message>, and <command-args> XML tags instead of parsed titles

Additional Context

• Reproduced in both WebStorm integrated terminal and standalone WSL terminal, so this is not IDE-specific.
• Sessions themselves are functional — they can still be resumed.
