- Around line 1247-1253: Replace the as any casts in this test with a TestState
type, using typed initial and next state values for the router and buildLocation
calls. For the reference check, narrow location.state to ParsedHistoryState &
TestState while leaving createTestRouter’s generic state type unchanged because
HistoryState is an extension point.

Replace as any with typed state values.
Define a TestState type, pass typed initial and next state values, and narrow location state to ParsedHistoryState & TestState for the reference check. createTestRouter cannot carry TestState because HistoryState is an extension point.
