The fix in issue #2 resolved a stale-closure bug in createPathSegment where
onClick captured graphsPath at render time; after further navigation findIndex
returned -1 and splice(0) wiped the entire breadcrumb array.
New test suite 'Stale-closure regression (issue #2)' covers:
- Root breadcrumb remains functional after navigating three levels deep
- Level-1 breadcrumb resolves correctly when clicked from level 3
- Successive back-clicks each trim exactly one breadcrumb level
- Clicking the currently active breadcrumb does not alter the path
