Variable PARAMETER_ID_PATTERN`Const`

PARAMETER_ID_PATTERN: "^[a-zA-Z][a-zA-Z0-9_]*$" = '^[a-zA-Z][a-zA-Z0-9_]*$'

Pattern for an App Action parameter's id. It cannot start with a number and _ is the only delimiter allowed, so a parameter stays reachable via dot notation in JavaScript.

Exported as a pattern string so it can be embedded directly in a JSON Schema pattern keyword.
