build(deps): bump lru from 0.16.1 to 0.16.3 in /test/simulator-graphical (#1741)
What changed, and why it matters
This is an automated dependency update by Dependabot that bumps the Rust 'lru' crate from version 0.16.1 to 0.16.3 inside a graphical simulator test component. The change only modifies a test-only lockfile and does not touch the actual BitBox02 firmware code. There is no indication in the commit that this fixes a security issue, and the supplied references do not mention any security relevance.
Treat as routine maintenance. If security relevance is suspected, review the upstream lru-rs 0.16.1 to 0.16.3 changelog for any disclosed fixes, but the commit itself provides no evidence of a security issue.
Security signals we found
Dependency bump in test-only code
Transitive dependency 'zeroize' added (memory-clearing utility, not a vulnerability signal)
No security-relevant description in commit message or title
Evidence from the diff
The commit updates an indirect dependency, lru 0.16.1 -> 0.16.3, in test/simulator-graphical/Cargo.lock. The diff also shows that the updated lru version pulls in an additional transitive dependency, zeroize. The change is confined to a test/simulator graphical harness and does not affect the embedded firmware build or runtime code. No CVE, advisory, or vendor security statement is present in the commit or supplied references.
