fix: Copy terminal selection on Linux

[seanpoulter]

This will close #103.

Problem

We assume the command to copy from the terminal is Ctrl--c:

[chrome 114.0.5735.289 linux #0-0] » /test/specs/bottombar.e2e.ts
[chrome 114.0.5735.289 linux #0-0] bottombar
[chrome 114.0.5735.289 linux #0-0]    ✖ can read from terminal @skipWeb

Proposed Changes

• fix: Copy terminal selection on Linux
• test: Enable passing tests

This is awesome 💯

I'll revert all the changes except changing the copy implementation. We have confidence it works. We can troubleshoot those other failing tests another day.
