Previously, this reassigned the local pointer (into = from), which did not modify the underlying node. Using *into = *from correctly overwrites the target node value.

also replaced shallow .Value comparison with structural deep equality. .Value works for scalar nodes but fails for mappings and nested structures.
@nderjung @craciunoiuc could you please take a look

Summary
This PR fixes scalar node merge behavior in RecursiveMerge
by replacing pointer reassignment with value overwrite.
It also improves sequence merging by introducing deep
node comparison, enabling proper handling of sequences
of mappings and nested structures.
Changes
Testing
All tests pass with:
go test ./internal/yamlmerger/...
