Autocomplete Reliability Issues - Inconsistent Behavior Across Projects
I'm experiencing persistent issues with Tailwind autocomplete that seem to affect many users based on the volume of similar issues in this repo. The core problem isn't configuration complexity, but rather the unpredictable and fragile nature of the autocomplete functionality.

The Pattern:

1. Spend 2-3 hours troubleshooting autocomplete issues
2. Try multiple solutions from various GitHub issues
3. Eventually something works (often unclear what specifically fixed it)
4. Days later, autocomplete stops working again with no configuration changes
5. Cycle repeats

The Challenge:
The current troubleshooting process requires testing dozens of different configuration permutations because minor variations can inexplicably affect functionality. This creates a frustrating trial-and-error debugging experience where:

• Working configurations in one project fail in seemingly identical setups
• Solutions that work today may fail tomorrow without any changes
• The relationship between configuration and functionality isn't predictable

What Would Help:

• More deterministic behavior - same config should produce same results
• Better error reporting when autocomplete fails to initialize
• Clearer documentation on what exactly the extension is looking for
• A diagnostic command to verify configuration is being read correctly

The autocomplete feature is incredibly valuable when it works, but the current reliability issues make it difficult to depend on. Has anyone found patterns or approaches that lead to more consistent behavior?
