Bug Description

Currently, once resumed, a session gets a very generic name in the "claude --resume" list. Currently, we don't have a way to explicitly rename the session, but for new sessions, there's a partial workaround, that name gets decided by the first question. Ideally, we should be able to name a session, so that resuming itis eariser, instead of going of hit and trial. But the resumed session overwriting that name makes it harder, even without this feature.

Steps to Reproduce

1. Start a session, do some work and close it.
2. Resume it (for now, it has somewhat sensible name in the "--resume" list), and then close it again.
3. Close it again, and then try to resume. All the sessions that go through this flow, end up with a generic "This session is being continued from a previous conversation..." name.
4. Even timestamp doesn't help, if there were multiple sessions resumed around the same time. (very common, when resuming work after a system or IDE restart)

Expected Behaviour

1. We should persist the session name, even after resume.
2. Even better, we should either have a way to explicitly give a name to a session (which persists across resuming)

Actual Behavior

Session names are lost after resume.
