[FEATURE] Feature request: Allow naming/labeling sessions for easier resume

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

When using /resume to continue a previous session, only session IDs and timestamps are shown. With many sessions across
different tasks, it's impossible to identify which session to resume without opening each one.

Proposed Solution

Allow users to assign a custom name or label to a session. For example:

• A command like /name "migrate to tencent CCR" to name the current session
• The name would appear in the /resume list alongside the timestamp

This would make it much easier to manage and resume the right session when working on multiple projects or tasks.
