Fold the fly-to vertical-centering fix into our patch-package patch (alongside
the existing spouse-layout fix) instead of compensating in app code, and revert
the in-app workaround so the two don't double-correct.
- patches/family-chart+0.9.0.patch: cardToMiddle now scales datum.y by the zoom
k in both dist builds (.js + .esm.js), matching datum.x. Verified the patch
applies cleanly (patch-package --error-on-fail).
- tree/page.tsx: the cardToMiddle caller passes raw y again (the patched library
does the scaling now); pre-scaling here too would double-correct. Behavior is
identical to the previous in-app fix — both center the node exactly.
- CLAUDE.md: documents the two family-chart patches, how to regenerate them, and
that both should be upstreamed. The cardToMiddle fix is submitted upstream
(donatso/family-chart#103, issue #102); the spouse-layout fix is a TODO.
The frontend Dockerfile already COPYs patches/ before npm ci, so the fix is in
the production build.
