5.1: memoize createRectificationShellSetters so the four shell setters keep a
stable identity across renders, then list the two the entry-summary effect uses
in its dependency array. Lint warnings 120 -> 119 with no new warning.
5.2: move the four synastry useStates and draftSynastryQuestionFromChart into
the new useSynastry hook. Home keeps only two stable callbacks the chart-library
effect calls; the chart-library dialog receives one spread synastryPanel object.
Zero behavior change, zero copy change.
