Add --host flag support to run:ios and run:android commands

[JakubKorytko]

Overview

Fixes: #681

This PR adds support for the --host flag in run:ios and run:android commands, allowing users to specify a custom host for the Metro development server when using the --dev-server flag. This brings feature parity with the existing rock start --host command.

Changes

Android (packages/platform-android/src/lib/commands/runAndroid/runAndroid.ts)

• Added host?: string to Flags interface
• Pass host: args.host to dev server initialization
• Added --host <string> option to runOptions

iOS (packages/platform-apple-helpers/src/lib/commands/run/)

• Added host?: string to RunFlags interface in runOptions.ts
• Pass host: args.host to dev server initialization in createRun.ts
• Added --host <string> option to getRunOptions in runOptions.ts

Documentation (website/src/docs/cli/introduction.md)

• Updated run:ios options table to include --host flag
• Updated run:android options table to include --host flag

Testing

The implementation follows the existing --port flag pattern for consistency. Users can now:

# Start iOS app with custom dev server host
rock run:ios --dev-server --host 0.0.0.0

# Start Android app with custom dev server host
rock run:android --dev-server --host 192.168.1.100

A member of the Team first needs to authorize it.

There's also a bunch of other options that we could pass to Metro, which will pollute the API, but for now this works 👍🏼
