Provide clientInput access to inputSchema

[gcmarcello]

Add support for dynamic input schema building using clientInput in the inputSchema method. The objective here is to be able to define or extend the schema based on the input itself when needed.

const submitFormAction = ac
  .inputSchema(async (clientInput) => {
    formRequireFullname = await checkForm(clientInput.formId)
    if (formRequireFullname) {
      return z.object({
        formId: z.string(),
        firstName: z.string().min(1),
        lastName: z.string().min(1),
        email: z.string().email(),
      });
    }
    
    // Default form - only display name
    return z.object({
      formId: z.string().optional(),
      displayName: z.string().min(1),
      email: z.string().email(),
    });
  })
  .action(async ({ parsedInput }) => {
    return { success: true, data: parsedInput };
  });
