Merge pull request 'fix(kugetsu): set GIT_EDITOR=cat for non-interactive git operations (fixes #70)' (#72) from fix/issue-70-git-editor into main

Set GIT_EDITOR and EDITOR to 'cat' in kugetsu init to prevent
vim from opening during git operations in headless mode.

This fixes issues where git rebase --continue would hang waiting
for vim TTY input in opencode sessions.

Fixes #70
