- New LogLevel type: Debug, Info, Warn, Error with Ord instance
- Logger holds configured level and output handle (stderr or file)
- --log-level and --log-file CLI flags
- log_level and log_file YAML config fields
- Log messages assigned appropriate severity levels
- Test logger updated to new Logger structure
- All 17 tests passing
git pull --no-edit fails with exit 128 on divergent branches because
fast-forward is impossible. Using --rebase handles divergent histories
by rebasing local commits on top of fetched remote commits, producing
a linear history without merge commits.
- src/Converge.hs: Change gitPull from --no-edit to --rebase
- test/GitPullSpec.hs: Update rebase test to expect success and
verify linear history (3 commits, no merge parents)
- test/*.hs: Clean up unused imports
