- Reject a value that does not fit a Nullable element of an Array, Tuple or Map
- Fix wrong results of in-order optimizations and primary key analysis over a CAST into `Bool`

- Fix `RESTORE ... ON CLUSTER` hanging when a creation-mode setting is `'create'` or `'must-exist'`
- Fix index analysis of a `FixedString(N)` key compared with a longer `String` constant ending in zero bytes
- Bool column added by ALTER is treated as UInt8 inside other columns' MATERIALIZED/ALIAS/DEFAULT expressions on old parts (toString gives 0, not false); vertical merge persists the wrong value
