Feature Request: Rename chat sessions

Summary

Add ability to rename chat sessions in Claude Code CLI for better organization and context tracking.

Current Behavior

• Chat sessions are tracked only by session ID and timestamp
• No way to give meaningful names to sessions
• Difficult to identify which session contains which work when reviewing history

Proposed Feature

Allow users to rename chat sessions, either:

1. Via a new command like /rename "Session Name"
2. Through a config file that maps session IDs to user-defined names
3. By prompting for a session name when starting a new session

Use Case

When working on multiple features or tasks:

• "Mobile PWA Implementation"
• "Trip Restock Workflow"
• "Database Migration"

Having named sessions makes it much easier to:

• Resume the right conversation context
• Review past work
• Organize development tasks

Alternative Workaround

Currently using /clear to start fresh sessions, but this loses valuable context and history.
