// Package wickra provides idiomatic Go bindings for the Wickra
// technical-analysis library over its C ABI hub.
//
// Each indicator is an opaque-handle type with a New<Indicator> constructor and
// Update/Batch/Reset/Close methods. Handles are freed by Close and, as a
// backstop, by a finalizer; call Close explicitly to release native memory
// promptly. The binding links against the prebuilt Wickra C ABI library, staged
// per platform under ./lib/<goos>_<goarch>/, with the C ABI header vendored
// under ./include. For distribution the libraries are committed alongside the
// source in the wickra-go module, so `go get` + `go build` works with no extra
// steps — see the package README.
