fix(custom-line-paragraph): correct paren-jump, line-join, and duplicate

This module carried three editing bugs.

cj/jump-to-matching-paren, with point on a closing delimiter, ran backward-sexp from there and landed on the last inner sexp instead of the opener. It now steps past the closer first so backward-sexp spans the whole expression, and restores point when the delimiter is unmatched. Four tests that asserted the last-inner-sexp landings are corrected to the true matching opener.

cj/join-line-or-region, without a region, added a newline unconditionally after joining, which left a stray blank line when joining a line in the middle of the buffer. It now adds the newline only at end of buffer.

cj/duplicate-line-or-region duplicated a stray empty line for a region ending at beginning-of-line and split the line for a region ending mid-line. I normalized the bounds to the whole lines the region touches and insert that block once.
