Release amend tool

[abitrolly]

• Move https://github.com/yakshaveinc/linux/blob/master/bin/amend-pr.sh script into separate repo
  • Use https://gitlab.com/esr/reposurgeon to carve out history with amend-pr.sh to be at the top of the repo
    • Find frontend for reposurgeon that allows to record interactive choices into script (like https://github.com/phord/git-split)

• Package amend as a snap (Release amend-pr.sh as amend-pr snap linux#25)
  • Setup CI/CD to avoid snap reupload
    • Create reproducible snap builds to compare with uploaded
      • Release ksykaitai to patch timestamps in .snap squashfs archive

reposurgeon works by loading the whole repo into memory, then filtering and modifying commits according to user commands, then saving the repo into new dir.

reposurgeon drawbacks:

stripped signatures

(doesn't apply) reposurgeon uses git fast-export/fast-import, which [strip commit signatures] (https://gitlab.com/esr/reposurgeon/-/issues/367). If reposurgeon is used to make a branch that needs to be merged back, this will move the branch point back to the first signed commit, rather than to leave it at firsts edited commit. In case of splitting a path to a different repo, this doesn't apply, because repos will likely be different right from the first commit.
