• Naming confusion with ARM Preflights (@rajeshkamal5050, @tg-msft, @vhvb1989)
• Lowercase DeploymentStateSkipped (@tg-msft)
• Use "canceled" instead of "abort" (@tg-msft)

What needs to change

1. Rename the feature from "preflight" to "validation" to avoid confusion with ARM Preflights. Consider naming convention like validation.provision to scale with future validation use cases.
2. Make DeploymentStateSkipped constant lowercase: "deployment state" instead of "Deployment State".
3. Replace "abort" terminology with "canceled" in UI-facing strings (e.g., PreflightAbortedSkipped → use "preflight canceled" language).
