Fix error throwing to use correct Bun error API

Browse Source 
Addresses CodeRabbit review feedback:

**Issue**: Used non-existent `Bun::throwError` function for error handling.

**Fixed**:
1. Detached buffer check: Use `throwVMTypeError` (matches line 784 pattern)
2. Unknown encoding check: Use `Bun::createError` + `scope.throwException`
   (matches line 2418 pattern)

Both error paths now follow established patterns in the codebase.

All tests still pass (22 custom + Node.js compatibility).
