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.

family-chart 0.9.0 stacks all of a person's spouses on one gender-determined
side, so someone with two spouses (e.g. a woman with two husbands) renders
with both spouses piled above/below her and ambiguous child lines.
Patch the library (via patch-package) so the person stays centered and their
spouses split to alternating sides — spouse 1 above, spouse 2 below, further
spouses farther out — and order each couple's children to match, so children
descend from between the correct pair without crossed lines:
- setupSpouses: keep the person centered; place spouses at alternating
offsets and recenter the cluster on the person's slot.
- sortChildrenWithSpouses: order children by spouse order (gender-independent)
to match the new spouse positions.
Adds patch-package + a postinstall hook, and COPY patches into the Dockerfile
deps stage so the patch applies during `npm ci` in CI. Verified the patch
re-applies on a clean install and the production build passes.
