The short version

What changed, and why it matters

This commit is a routine version bump for the base58ck crate from 0.4.0 to 0.5.0. It only updates version numbers in package manifests, lock files, and adds a changelog entry describing unrelated feature changes. There are no code changes, bug fixes, or security patches in this commit itself.

Recommended action

No security action needed. This is a release preparation commit. Review the actual code changes in the referenced PR #6505 separately if assessing the security of the 0.5.0 release.

Security signals we found

No strong security signals were identified.

Technical analysis

Evidence from the diff

The commit updates base58ck dependency references from 0.4.0 to 0.5.0 across Cargo.toml files and lock files. It also adds a changelog entry for version 0.5.0 mentioning API changes (Base58CkString replacement, bitcoin_hashes stable upgrade). The actual functional changes referenced in the changelog are from a separate pull request (#6505) and are not present in this diff.
