[OTHER] Improve Error Message Clarity

[aturker-synnada]

Summary

Some error messages in the library are insufficient and do not provide enough context for users to diagnose issues effectively. Enhancing these messages will improve debuggability and usability.

Context

Currently, certain error messages lack key information:

• set_shapes Function: When a non-Tensor error occurs, the message should include the name of the corresponding key. Additionally, if multiple errors exist, they should be aggregated and displayed together rather than stopping at the first encountered issue.

• unnamed_data_keys Error: The current error message prints connection dollar names ($ prefixed identifiers), which can be unclear. Instead, the full connection name should be displayed for better readability.
