Improve Cursor Semiform rules

[praisethemoon]

Right now cursor generates some rules as follows:

/**
 * Calculator button component
 */
component CalcButton {
    /** Text to display on the button */
    label: String
    onClick: String
}

The goal of semiform is to have such details handled by the LLM and not necessarily present in the DSL.

Goal:

Properly document that the properties of UI components are rather high level properties and not fine-granied such as styles events etc, Except if the logic is too complex and may need to be modeled as such.
