Improve Session ID Visibility for Easier Recovery (make it visible on startup)

[m-tantan]

Describe the feature or problem you'd like to solve

Display session ID prominently for easier identification and recovery after crashes

Proposed solution

When the terminal freezes and needs to be force-closed, there's no way to disable Copilot gracefully. This means there's no session ID readily available to restore the session.

Current behavior:

• Session IDs are not visible or easily accessible during active use
• After a crash, multiple sessions exist with no clear way to distinguish between them
• Users must recall their starting prompt to identify the correct session
• Session IDs all look similar, making it difficult to identify which is which

Expected behavior:

• Session ID should be visible from the start of the session
• Users should be able to easily copy the session ID
• Sessions should be more distinguishable (e.g., show timestamp, first prompt preview, or a memorable identifier)

Impact:

• Time lost trying to locate the correct session after a crash
• Frustration when multiple sessions exist with no clear differentiation
• Risk of losing work context when the wrong session is restored

Suggested improvements:

1. Display the session ID in the UI header or status bar
2. Add a "Copy Session ID" button
3. Include additional metadata (timestamp, first prompt snippet) in the session list
4. Consider user-friendly session names or aliases
