The short version

What changed, and why it matters

This commit is a routine maintenance update for the BitBox02 hardware wallet firmware. It upgrades the pinned Rust compiler toolchain from an older version to Rust 1.96.0, updates the project's Docker build container and related developer tools (like clang-format and clang-tidy) from version 21 to 22, and refreshes several vendored Rust library dependencies to newer versions. The only application code change is a small test-only cleanup in the Bitcoin transaction signing tests to satisfy a new Rust linter warning. There is no direct evidence in the commit message or diff that this fixes a specific security vulnerability.

Recommended action

Treat as a normal maintenance commit. Verify the firmware build and test suite pass with Rust 1.96.0 and the updated container. Review release notes of the vendored dependencies (especially libc and secp256k1-sys) for any security fixes that may affect the target architecture, but no immediate security action is required based on this commit alone.
