Update latest v2

[tznind]

• Copy paste with Ctrl+C pastes code in due to native console intercept, Undo does not properly revert (BUG: Actually reverts the last operation)

  Console.Write("\x1b[?2004h"); // enable

  // In your input read loop:
  // \x1b[200~ = paste start → buffer following chars
  // \x1b[201~ = paste end   → handle buffered string as paste

  Console.Write("\x1b[?2004l"); // disable on exit

@tig @BDisp ok this is basically ready for review, I've a few more views to work through (see checklist at top) but everything seems to be working at least as well as the last release which targetted 2.0.0-develop.4538

Check out the PR and kick the tyres.

I've also beefed up the showcase project as I work through QA on the various controls we have.
