junk 1.0.0

First junk release, a personal fork of hunk 0.22.0.

Changes over hunk

• fix: the review and commit pickers open without the lazy-load delay
• feat: ctrl+shift+P lists the review's commits and opens one at a time

• feat: the files pane can close a folder again
• feat: the files pane joins a lone directory chain into one row

• test: match junk's menu bar in the PTY waits
• feat: reveal a gap from either end, below the last hunk too, and by mouse
• feat: arrows step every line, j/k stay in the hunk, and navigation respects collapsed files
