Describe the bug

When AI agent is writing about approximates it uses a single tilde ~ e.g., ~2000. When it does a few approximations in one line it gets rendered as markdown strikethrough. However, according to my research (see sites like https://www.markdownguide.org/extended-syntax/#strikethrough) it should only do strikethrough if we bookend with double tilde ~~.
Please fix the renderer so it requires double tilde and doesn't strikethrough random parts of output.

Additional note: it seems to only happen if the tildes are inside parentheses: "Make a fix (~2000 lines) and delete old file (~5000 lines)", rendering tilde outside the parentheses works fine. I think it's probably a regex bug or something.

Affected version

1.0.2

Steps to reproduce the behavior

1. Use this prompt: `I'm testing a bug with your markdown rendering, print this line exactly: "Make a fix (~2000 lines) and delete old file (~5000 lines)"
2. You can also have it test another line like "There are ~100 ways this bug might appear and ~5 ways to fix it ~10% of the time" and see that it renders fine

Expected behavior

Make sure the markdown only does strikethrough when ~~ is used.
