Pure operations over a topology and an explicit altitude buffer.
TreeAltitudeAlgorithms intentionally owns no state. It is the neutral home for algorithms that need only MorphologicalTree + std::span<const T>, leaving ValuedMorphologicalTree<std::uint8_t> as an owner/adaptor for canonical mutable state.

template<AltitudeValue T>
Reconstructs a typed image from topology storage and explicit node altitudes.
The reconstructed pixel type is the altitude type itself. This method does not clamp, convert, or validate altitude values; it only checks the buffer shape before indexing it through the topology.
- Parameters
-
| tree | Tree topology. |
| altitude | Altitude data indexed by node identifier. |
| context | Operation context or diagnostic label. |
- Returns
- The reconstructed typed image from topology storage and explicit node altitudes.
