Fix aware in select option

[ganyicz]

The scenario

Using indicator="checkbox" on a <flux:select> listbox doesn't have any effect with Blaze:

<flux:select variant="listbox" indicator="checkbox" multiple>
    <flux:select.option value="1">Option 1</flux:select.option>
    <flux:select.option value="2">Option 2</flux:select.option>
</flux:select>

The problem

The @aware directive in select/option/index.blade.php didn't include indicator, so Blaze didn't propagate it through the delegate component:

flux:select (indicator="checkbox")
  └ flux:select.option — @aware(['variant']) ← indicator not included
      └ flux:delegate-component
          └ flux:select.option.variants.custom — @aware(['indicator'])

The solution

Add indicator to the @aware directive in select/option/index.blade.php

@aware([ 'variant', 'indicator' ])
