feat: add focus_after_send option for terminal behavior

[ThomasK33]

Add focus_after_send option to control terminal focus behavior

Added a new configuration option focus_after_send that controls whether the Claude terminal should be focused after a successful send when already connected.

When enabled, the terminal will be focused after sending code to Claude. When disabled (the default), the terminal will only be made visible but not focused.

This provides more control over the workflow when interacting with Claude:

• Default behavior (false): Terminal becomes visible but doesn't steal focus
• Optional behavior (true): Terminal becomes visible and focused after sending

The PR includes:

• Configuration option in the main config structure
• Type definition updates
• Implementation in the send_at_mention function
• Documentation in README.md
• Unit tests to verify both behaviors
