## What changed Enabled `clippy::std_instead_of_alloc` and `clippy::std_instead_of_core` for the targeted crates and the workspace-inheriting `libdd-trace-obfuscation` crate. Applied the resulting mechanical imports and path rewrites from `std` to `core` or `alloc` where available. Merged the latest `origin/main` into this branch and renamed the branch to `refactor/clippy-core-alloc-imports`. ## Why This narrows standard-library dependencies where the APIs are available from `core` or `alloc`, supporting the repository no-std compatibility work. ## Validation - `cargo +nightly-2026-02-08 fmt --all -- --check` - `cargo +stable clippy --workspace --all-targets --all-features -- -D warnings` Replacement for closed PR #2116.
