`Container` throws `TypeError [ColorConvert]` when `accentColor` is omitted (docs say optional)

[ItsRayanM]

Bug Summary

<Container> crashes at runtime when accentColor is not provided, even though ContainerProps documents accentColor as optional.

This causes command execution to fail for any Components v2 message using <Container> without an explicit color.

Affected Version

• commandkit: 1.2.0
• discord.js: 14.25.1
• Node.js: v24.12.0
• OS: Windows 11 (NT 10.0.22631.0)

Minimal Reproduction

import { type ChatInputCommand, Container, TextDisplay } from 'commandkit';

export const command = {
  name: 'repro',
  description: 'Reproduce container accentColor crash',
};

export const chatInput: ChatInputCommand = async (ctx) => {
  const container = (
    <Container>
      <TextDisplay content="Container without accentColor" />
    </Container>
  );

  await ctx.interaction.reply({
    components: [container],
    flags: ['IsComponentsV2'],
  });
};

1. Register and run /repro.
2. Command fails with a runtime exception.

Actual Result

Command execution fails with:

TypeError [ColorConvert]: Unable to convert "undefined" to a number.
    at resolveColor (.../node_modules/discord.js/src/util/Util.js:299:11)
    at Container (.../node_modules/commandkit/src/components/display/container.ts:43:15)
    ...

Expected Result

If accentColor is omitted, <Container> should render normally without throwing.

Why This Seems Like a Framework Bug

The docs/API indicate accentColor is optional (accentColor?: ColorResolvable).

From observed behavior and stack trace, container logic appears to call resolveColor even when accentColor is undefined.

Suspected conditional issue in container implementation:

• If code checks typeof props.accentColor != null, that condition is always true because typeof returns a string ("undefined", "string", etc.), never null.

Suggested Fix

Guard directly on the value, not typeof:

if (props.accentColor != null) {
  container.setAccentColor(resolveColor(props.accentColor));
}

Workaround (for users)

Pass accentColor explicitly on every <Container> until fixed.
