Move forEach from Array to Task to Avoid Cyclic Dependency

[NickSeagull]

Currently, the forEach method is defined in the Array module and is responsible for iterating over each element while executing an IO action. However, in NeoHaskell, side-effectful functions should use Task instead of IO.

Attempting to fix this by importing Task into the Array module leads to a cyclic dependency. To resolve this, forEach should be moved to the Task module and implemented using the Traversable type class. This would allow forEach to work generically over any collection type that supports traverse, ensuring proper separation of concerns and avoiding cyclic dependencies.

Expected Solution

• Move the forEach implementation from Array to Task.
• Modify forEach to use Traversable instead of being specific to Array.
• Ensure forEach can be used in for loops over any collection that implements Traversable.
• Remove the now-unnecessary implementation of forEach in Array.

Additional Context

This change aligns with NeoHaskell's design philosophy by ensuring that effectful computations use Task, rather than IO, and by leveraging Traversable to generalize the iteration process.
