Add timestamps to chat messages

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

Summary

Add a timestamp display to each message in the Claude Code
chat interface, so users can see when each message was sent.

Motivation

When working on long sessions, it's useful to know how long
a session has been running and when a specific exchange took place.
Currently there is no way to tell without checking external clocks.

Proposed behavior

• Show a timestamp (e.g. 14:32) next to each message
• Optionally show elapsed time since session start
• Could be toggled on/off in settings
