# Purpose: Provide shared SDK path normalization for release smoke/package scripts.
# Key exports: plasmite_normalize_sdk_dir <input-dir> <staging-dir> [context-label].
# Role: Convert raw cargo output layouts into stable SDK bin/lib layout when needed.
# Invariants: Returned directory always contains bin/plasmite(.exe) + lib shared library.
# Invariants: Windows staged SDKs preserve import-library artifacts needed for relinking.
# Invariants: Normalized SDK inputs are returned unchanged and are never copied.
# Invariants: Staged outputs only include required runtime artifacts and optional static library.
# Notes: Intended to be sourced by scripts; emits actionable errors to stderr.
