What ） means
It closes an aside opened by （. In （補足）, the marks set off an extra note; the words inside carry the meaning.

Japanese typesetting used both half-width and full-width punctuation; later text encodings—ways computers stored Chinese, Japanese, and Korean writing—kept the width forms separate so text could be converted back to older formats without losing that choice.
How do I type the zenkaku parenthesis?
In a Japanese input method, choose Zenkaku punctuation. Microsoft Japanese IME labels its width switch Hankaku/Zenkaku; when both forms are offered, select the full-width candidate.

Can ） mean laughter?
Only as the closer in a larger Japanese tag. A 2021 account of Japanese internet writing describes （笑） as a written laughter tag. The character 笑 means “laughter” and supplies the mood; ） only closes the tag.
Neutral punctuation in Japanese or Chinese text; in Latin-only text, the full-width form reads as a width mismatch.
