Research direction

No source file or test is named. Start by reproducing the exact macro keys, qqiexampletextEscq@q, in the reported VSCode and VsCodeVim versions, then trace macro execution until the recursion occurs. Done means an infinite macro no longer requires a VSCode restart and @q remains undefined as expected.
