feat: improve error handling in work item tools

[danhellem]

This pull request improves error handling in the configureWorkItemTools function within src/tools/work-items.ts by wrapping all handler logic in try/catch blocks and returning structured error responses instead of throwing exceptions. Additionally, related tests in test/src/tools/work-items.test.ts have been updated to expect these new error response formats. This change ensures more consistent and user-friendly error reporting across all work item operations.

Error handling improvements:

• All handler functions in configureWorkItemTools are now wrapped in try/catch blocks, returning structured error objects with isError: true and descriptive error messages when exceptions occur.

Test updates:

• Updated tests in test/src/tools/work-items.test.ts to check for the new error response structure, verifying that isError is true and that error messages are included in the response content. [1] [2]

consider introducing a utility method that does the try-catch and takes a handler and error message, this could be re-used for all of these tools instead of explicitly adding a try-catch in each tool
