[FEATURE]: CLI resume hint should render the command separately from the "Continue" label

Feature hasn't been suggested before.

• I have verified this feature I'm about to request hasn't been suggested before.

Describe the enhancement you want to request

When OpenCode exits, it displays the resume hint like this:

Continue  opencode -s ses_...

The "Continue" label appears on the same line as the command. This makes the command inconvenient to select and copy in a terminal: triple-clicking selects the entire line instead of just the command, requiring you to click and drag with the mouse.

Please render the command on its own line, or provide a dedicated copy-friendly output, for example:

Continue
opencode -s ses_...

I realize this is an extremely minor issue, so no worries at all if you decide to close it lol.
