Implement Wordle Scoring / Build a Form (Practical)

Question

## Problem

Implement Wordle's guess-scoring (greens/yellows/greys handling duplicate letters), or build a small React form with validation (reported Retool tasks).

## Example
```
scoreGuess("allol","hello") -> correct green/yellow/grey pattern
```

## Constraints
- Handle duplicate letters correctly

## Approach
Two passes: greens first, then yellows from remaining letter counts.
