_{Comparing refactor/actionable (96ee7bb) with main (84c9cea)}

📝 Walkthrough

Walkthrough

The CLI now uses ActionableError for lock conflicts and several validation and loading failures. Lock messages can identify the affected output directory. Interactive-session helpers now reside in stdout.ts, while the duplicate console helper was removed. Unit tests verify formatted lock errors and output-directory details.

Protect the ActionableError type contract in both lock-conflict tests.

The current assertions pass when a generic Error contains the expected message.

• packages/nuxt-cli/test/unit/commands/analyze.spec.ts#L158-L162: assert that the rejection is an ActionableError.
• packages/nuxt-cli/test/unit/commands/build.spec.ts#L128-L132: assert that the rejection is an ActionableError.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Preserve output context when outputDir is empty.

If a caller passes '', this truthiness check emits the generic “already running” message. Treat undefined as the absent-value case and render an empty relative path as ..

Proposed fix

-    options.outputDir
-      ? `Another Nuxt ${label} is already writing to ${options.outputDir}:`
+    options.outputDir !== undefined
+      ? `Another Nuxt ${label} is already writing to ${options.outputDir || '.'}:`
