+// StripMarkdown converts Markdown-formatted text to clean plain text.
+// Useful for platforms that don't support Markdown rendering (WeChat, LINE, etc.).
+//
+// Note: the underscore forms of bold (`__bold__`) and italic (`_italic_`) are
+// intentionally not stripped. The patterns `_..._` and `__...__` are
+// indistinguishable from snake_case and dunder identifiers (`my_func_name`,
+// Python's `__init__`), and stripping them silently corrupted code-related
+// text into things like `myfuncname` or `init`. Agents reliably emit the
+// asterisk forms (`**bold**`, `*italic*`), so dropping the underscore forms
+// is the safe trade-off here. Inputs containing literal `_italic_` will keep
+// their underscores; this is a small cosmetic loss vs. losing identifier
+// integrity in TTS / LINE / WeChat output.
