Add configuration options for timeout

**Problem**
When working with store, the error messages could be more descriptive.

**Suggestion**
Improve error handling and add detailed error messages.

**Context**
This would help with debugging and maintenance.

The issue names store error handling but does not identify files, tests, commands, or an entry point. Start by locating the store implementation and its existing error messages, then determine the expected detailed wording and add coverage for the affected failures.
