fix(gmail): treat --body - as read-from-stdin sentinel

plosson · claude · plosson · commit f5f699d9b009 · 2026-07-03T10:00:02.000+02:00
Passing `--body -` set the body to the literal "-" because parseBody only
fell back to stdin when --body was entirely absent. Piping a heredoc through
`--body -` therefore lost the message body. Now a bare "-" is treated as an
explicit stdin sentinel, matching the common CLI convention. Applies to both
`gmail send` and `gmail draft` (shared parseBody).
