2 * Matches any XML-like `<tag>…</tag>` block (lowercase tag names, optional
3 * attributes, multi-line content). Used to strip system-injected wrapper tags
4 * from display titles — IDE context, slash-command markers, hook output,
5 * task notifications, channel messages, etc. A generic pattern avoids
6 * maintaining an ever-growing allowlist that falls behind as new notification
7 * types are added.
8 *
9 * Only matches lowercase tag names (`[a-z][\w-]*`) so user prose mentioning
10 * JSX/HTML components ("fix the <Button> layout", "<!DOCTYPE html>") passes
11 * through — those start with uppercase or `!`. The non-greedy body with a
12 * backreferenced closing tag keeps adjacent blocks separate; unpaired angle
13 * brackets ("when x < y") don't match.
