stackedprs-cli v0.0.15

TODO

• meta - move these into github issues
• list: lists main and items
• dx options
  • running next without start - give a hint and option to run start
  • replace start/next with "new" with meaning inference
  • new will always create a new branch based on the branch at the top of the stack
• up/down command options - rebases up or merges
  • all branches
  • just adjacent
• convert PR title into template and not hard coded
• When collapsing, each pr should have a single squashed commit in the commit log. Main->a->b Squash a in place, squash b onto a, merge a onto main, merge main onto master
• interface to drag and drop commits between stack items
