Summary

Cleaned actions/setup/js/messages_core.cjs and added a comprehensive test suite.

Context type: github-script (uses core global)

Changes

messages_core.cjs

1. Moved lazy require() to top-level import — error_helpers.cjs was required inside getMessages() on every call. There's no circular dependency, so it belongs at the module top level like all other imports.

2. Simplified toSnakeCase() with Object.fromEntries + flatMap — replaced the imperative for loop + two assignments with a functional one-liner. The new version also avoids duplicate entries when a key is already in snake_case (e.g. run_url previously got assigned twice):

   // Before
   const result = {};
   for (const [key, value] of Object.entries(obj)) {
     const snakeKey = key.replace(/([A-Z])/g, "_$1").toLowerCase();
     result[snakeKey] = value;
     result[key] = value;  // duplicate if already snake_case
   }
   
   // After
   return Object.fromEntries(
     Object.entries(obj).flatMap(([key, value]) => {
       const snakeKey = key.replace(/([A-Z])/g, "_$1").toLowerCase();
       return snakeKey === key ? [[key, value]] : [[snakeKey, value], [key, value]];
     })
   );

messages_core.test.cjs (new file)

Added 17 tests covering all three exported functions:

Validation ✅

• Formatting: npm run format:cjs ✓
• Linting: npm run lint:cjs ✓
• Type checking: npm run typecheck ✓
• Tests: npm run test:js ✓ (all 17 new tests pass; existing failures are pre-existing environment issues unrelated to this change)
