Allow one-off Browserstack CI dispatch with custom websocket URL

[pvditto]

Summary

This PR adds optional input parameters to all BrowserStack workflows, enabling testing of new Ditto cloud deployments with custom configuration.

Supported workflows:

• android-kotlin-ci.yml
• swift-ci.yml
• javascript-web-browserstack.yml
• android-cpp-browserstack.yml

All workflows now accept these optional inputs (all default to repository secrets when not provided):

• websocket_url - Custom Ditto websocket URL
• app_id - Custom Ditto app ID
• playground_token - Custom Ditto playground token
• auth_url - Custom Ditto auth URL

React Native Fix

• Fixed React Native app to actually use the DITTO_WEBSOCKET_URL environment variable
• Previously it was defined in env.d.ts but not used in the transport config
• Now properly configures websocket URL via updateTransportConfig

Usage

Automatic Dispatch with Script

The scripts/cloud-smoke-test.js script can dispatch all BrowserStack workflows and monitor their progress:

Basic usage (uses environment variables for all config):

node scripts/cloud-smoke-test.js

With custom websocket URL:

node scripts/cloud-smoke-test.js --websocket-url wss://staging.example.com/ws

With multiple custom parameters:

node scripts/cloud-smoke-test.js \
  --websocket-url wss://staging.example.com/ws \
  --app-id staging-app-id \
  --playground-token staging-token

All available options:

• --websocket-url <url> - Custom websocket URL
• --app-id <id> - Custom app ID
• --playground-token <token> - Custom playground token
• --auth-url <url> - Custom auth URL
• --help - Show help message

All parameters are optional and fall back to these environment variables:

• DITTO_WEBSOCKET_URL
• DITTO_APP_ID
• DITTO_PLAYGROUND_TOKEN
• DITTO_AUTH_URL

The script will:

1. Validate inputs
2. Dispatch all 4 BrowserStack workflows in parallel
3. Monitor progress with colored output
4. Wait up to 45 minutes for completion
5. Report final results
6. Exit with appropriate status code (0 = success, 1 = failure)

Manual Dispatch

To test individual workflows manually:

1. Go to Actions tab → Select any supported BrowserStack workflow
2. Click "Run workflow"
3. Enter custom values in the input fields (optional)
4. Leave fields blank to use defaults from secrets

All parameters are completely optional - workflows will use repository secrets as defaults when inputs are not provided.
