Creation and editing, the largest parity gap:
- issue create and mr create from the list screens; title/body edit on both detail screens; milestone picker on issues (milestone list + none to clear)
- Fixes a latent bug shipped in !1: stdin-carrying writes (mr comment, diff-comment --reply, issue comment) sent bare stdin, but bodyFrom only reads stdin when argv carries --file - — verified against production, bare stdin returns exit 2 "empty comment". All stdin writes now pass --file -.
- mr create branches are typed, not picked (no branch-list command yet, krz/gitbay#45); target prefills from repo show
91 tests green. issue create/edit verified live via the API with the app's exact argv; this MR was itself created through POST /api/v1/cmd with the app's mr create argv shape.
