A resume snapshot written before this change carries `selectedToolName`
where `ToolsUiState` now expects `selectedToolKey`. The blind cast in
`restoreTabUiFromSnapshot` carried it through as a stray field that would be
re-serialized on the next redirect. Route the Tools entry through a
`normalizeToolsUi` that drops it explicitly instead.
The name is deliberately not migrated to a row key: a snapshot lives for one
redirect (so this only arises when the app is upgraded mid-flight), and the
tools list is fetched after reconnect, long after restore — there is nothing
to resolve the name against. The selection is lost; search, form values, and
the run-as-task toggle restore intact.
