Enhancement: Improve GHC error messages

[aneilmac]

The error messages are unfriendly when using the GHC kernel.

For example a cell containing: (1 :: Int) / 2

produces the following error:

panic! (the 'impossible' happened)
  GHC version 9.15.20260331:
	<interactive>:1:12: error: [GHC-39999]
    • No instance for ‘Fractional Int’ arising from a use of ‘/’
    • In the expression: (1 :: Int) / 2
      In an equation for ‘it’: it = (1 :: Int) / 2

Please report this as a GHC bug:  https://www.haskell.org/ghc/reportabug

Ideally, the error message should not expose the panic! and leave the user with just the salient information:

<interactive>:1:12: error:
    * No instance for (Fractional Int) arising from a use of `/'
    * In the expression: (1 :: Int) / 2
      In an equation for `it': it = (1 :: Int) / 2
