Splits the
TableStrategywriter into a dtype and override dependent dispatcher, and a struct writer.StructStrategy— a structural writer that only shreds struct streams. It transposes a struct chunk stream into one ordered stream per field (plus validity when nullable) and writes each through a child strategy resolved by direct field name (field_writersentry, elsedefault; validity throughvalidity). It is intentionally dtype-unaware and knows nothing about nested dtypes or field-path overrides; it bails on non-struct input.TableStrategy— now a dispatcher.write_streamroutes on the stream's dtype and configured per-field overrides.TableStrategycontinues to own the field-path overrides and resolves the per-field child strategies before handing them toStructStrategy.This lets the writer dispatch different layout kinds per dtype — e.g. a list layout for list columns when a list strategy is configured — instead of
TableStrategyhard-coding struct shredding as its only nested behavior.
