Note

Low Risk
Lockfile-only indirect dependency upgrade with no app code changes; risk is limited to transitive crypto/SSH behavior in dependencies.

Overview
Bumps the indirect golang.org/x/crypto module from 0.45.0 to 0.52.0 in go.mod and go.sum, with matching checksum updates. The resolver also moves golang.org/x/sys (0.38.0 → 0.45.0) and golang.org/x/text (0.31.0 → 0.37.0) as part of the same dependency graph.

There are no application source changes; this is a Dependabot dependency refresh only. The newer x/crypto release includes several SSH client/server hardening and bugfix commits (deadlocks, option bypass, key limits, etc.) that apply to code paths used by transitive dependents (e.g. crypto-related packages in the module tree), not new logic in this repo.
