Fix CI failures: remove unused helpers and disable CUDA

This commit fixes two CI failures:

1. Removed unused pointer helper functions (boolPtr, stringPtr, int64Ptr,
   float64Ptr) that were flagged by golangci-lint as unused

2. Disabled CUDA feature for Rust candle-binding builds in CI by adding
   --no-default-features flag to cargo build commands, since CI runners
   don't have CUDA/nvcc installed

All 35 tests still pass locally after these changes.
