Bob Nystrom 2490e6a425 feat: add subscript operator for array indexing and string character access ...

Implement the `[]` subscript operator as an infix parser at `PREC_CALL` precedence, compiling to a method call on the receiver. Add a `string_subscript` primitive that handles integer indices (including negative for reverse indexing), returns `null` for out-of-bounds or non-integer arguments, and returns a one-character string. Register the `[ ]` method on the string class and include tests for basic indexing, negative indices, out-of-bounds, wrong types, and non-integer indices.
