- Require `namedCurve` to be `NODE-ED25519`
- Gate `Ed25519` usage behind feature detect
- Use `Ed25519` algorithm object instead of string
- Override `sign`, `verify` methods too
- Do not require `importKey` to be within `RequestContext`
- Automatically add `public: true` when importing `NODE-ED25519` keys
- Upgrade `@types/node` for improved `webcrypto` types
- Add tests for other algorithms using modified methods
