Ensures exactly one hyphen between prefix and issue number regardless of
whether user provides trailing hyphen.
Before:
bd init --prefix wy- → Issues: wy--1, wy--2 (double hyphen)
bd init --prefix wy → Issues: wy-1, wy-2 (single hyphen)
After:
bd init --prefix wy- → Issues: wy-1, wy-2 (single hyphen)
bd init --prefix wy → Issues: wy-1, wy-2 (single hyphen)
The hyphen is added automatically during ID generation in CreateIssue(),
so the stored prefix should never include trailing hyphens.
