crypto: Bump version to 0.2.0
Bump the `crypto` version. Update the dep in `bitcoin` and add an
explicit version number in `taproot-primitives`.
In preparation add a changelog entry, bump the version number, and
update the lock files.
What changed, and why it matters
This commit is a routine version bump for an internal Rust library called `bitcoin-crypto` from version 0.1.0 to 0.2.0. It updates version numbers in package files, lock files, and a changelog. There are no code changes that fix or introduce security behavior.
No security action needed. Treat as normal maintenance/release preparation.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The commit only modifies metadata: Cargo-minimal.lock, Cargo-recent.lock, bitcoin/Cargo.toml, crypto/CHANGELOG.md, crypto/Cargo.toml, and taproot-primitives/Cargo.toml. It bumps bitcoin-crypto to 0.2.0 and updates dependent crates to require the new version. The changelog notes API changes (re-exports, removed From impls, removed bitcoin-io dependency), but the diff itself contains no functional code.
