Implement error handling and improve resiliency for core and work

[danhellem]

This pull request enhances error handling and testing for the configureCoreTools and configureWorkTools functions. It introduces robust error management for API calls, ensures proper handling of null or empty results, and adds comprehensive test cases to validate these scenarios.

Error Handling Enhancements:

• Core Tools (src/tools/core.ts):

  • Added try-catch blocks to handle errors during API calls in getTeams and getProjects methods. Errors are now returned with descriptive messages, and null results are handled gracefully. [1] [2] [3] [4]

• Work Tools (src/tools/work.ts):

  • Introduced try-catch blocks for API calls in getTeamIterations, createOrUpdateClassificationNode, and postTeamIteration. Added checks for null or empty API results and provided meaningful error messages. [1] [2] [3] [4] [5]

Test Coverage Improvements:

• Core Tools Tests (test/src/tools/core.test.ts):

  • Added test cases to verify error handling for getProjects and getTeams methods. Tests ensure proper behavior when API calls fail or return null results. [1] [2]

• Work Tools Tests (test/src/tools/work.test.ts):

  • Added test cases for getTeamIterations, createOrUpdateClassificationNode, and postTeamIteration to validate error handling and null result scenarios. [1] [2] [3]
