v1.0.0

🔥 Release preview

Runs are now idempotent: the same source commits always produce the same monorepo hashes, so pushing twice is a no-op. No more forced pushes on every run.

# First run - pushes new commits
uv run python git-contribution-mapper.py
bash scripts/monorepo-push.sh

# Second run - nothing to push
uv run python git-contribution-mapper.py
bash scripts/monorepo-push.sh
# → Everything up-to-date

🚀 Features

• Add --dry-run / -n flag to preview what would run without making changes
• Add --force-push flag for when upstream history has changed
• Support any Git host, not just GitLab (#8)
• Configure the main branch per-repository via MAIN_BRANCH env var (#2)

🐞 Bug fixes

• Fix idempotent runs: set committer date = author date so cherry-picks are deterministic (Fixes #3)
• Fix linear history: use cherry-pick instead of merge to avoid merge commits in the monorepo (Fixes #7)
• Fix commit deduplication: include commit hash in blob content so identical-content commits are preserved (Fixes #4)

💻 Code quality

• Replace os.system() shell call with shutil.copy() to prevent command injection (#10)
