Keep the project board in step with commits

A post-commit hook moves the cards a commit references (Closes #N to
Fait, other #N to En cours) and adds a closed Fait card for an
unreferenced commit on main. A post-rewrite hook carries the commit
hashes over amends and rebases. Enable with
git config core.hooksPath .githooks.
