fix(status): banner Details strips Markdown syntax, not every #, _, >, * (#308)

plain() deleted those characters everywhere, so "join #lotus-general"
lost its #, snake_case and @some_user lost underscores, "->" became
"-", "5 * 3" became "5  3", and "<b>" became "<b". Strip only syntax:
heading / quote / list markers at line start, paired **x** *x* _x_ `x`,
and HTML tags.

Fixes #308
