feat: add machine hostname to CLI interface

[themactep]

Description

When running multiple Gemini CLI instances over SSH on different hosts, it is very easy to get lost or confused about which host you are currently interacting with.

Proposed Solution

Include the machine's hostname in the CLI interface (e.g., in the header, prompt, or a dedicated status line). This will provide immediate visual confirmation of the current environment.

Expected Behavior

The CLI should display the hostname (e.g., Gemini CLI (lapcat) or similar) so users can distinguish between different sessions.

Thank you for the suggestion! Adding the machine's hostname to the CLI interface (header or status line) is a great way to improve clarity for users working across multiple SSH sessions. We are labeling this as 'help wanted' and would welcome a pull request implementing this feature.
