[FEATURE] Add task summary when resuming sessions

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

Comment:
When using the /resume command to continue a previous task,
it would be helpful to display a one-line summary title at
the beginning showing what the task was about.

Example:
"[Resume] Gmail report automation - removed duplicate items
and adjusted email formatting"

This would make it immediately clear which task is being resumed.
