Show full screen output on Wait+Line mismatch

[3v1n0]

Is your feature request related to a problem? Please describe.

Thanks to @mastercactapus we've finally the Wait feature, but when waiting for a line on failure it's hard to understand the context as the error is just:

failed to execute command: timeout waiting for "Line Username:$" to match Username:$; last value was: >

Describe the solution you'd like

Other than showing the failed line (ideally in a new line so that's clearer), the whole context should be shown as when using Wait+Screen

Describe alternatives you've considered
Using Wait+Screen /Username:\n/ is an option but that doesn't make sure that we're matching the last screen line.

I can see how that would help debugging -- we could print the entire buffer, though it would be important to indicate which line the cursor is on (since that's the one being checked).

For your issue, the last line is likely the cursor, but if that ever weren't the case, it would help understand what happened.

That sounds good. It looks like there's definitely room for improvement with the error message here for sure. It would be nice to have the error message similar to the one we will be using in Freeze

Here's the code behind this output: https://github.com/charmbracelet/freeze/pull/119/files#diff-097efd4fdcfbc4644e1d6fd6b758f217ca51969e14309c8b70d42a6e41dde579
