Claude Bot eb3a23ab03 fix: resolve stale closure causing breadcrumbs to disappear on back-navigation (closes #2 )

The onClick handler in createPathSegment closed over the graphsPath variable
from the render when the segment was created. By the time a breadcrumb was
clicked (after further navigation), that closure was stale, so findIndex
returned -1 and splice(0) wiped the entire breadcrumb array.

Fix: use the functional updater form of setGraphsPath so findIndex runs
against the current state rather than a stale snapshot.
