<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> **Low Risk**
> This PR is a release/versioning + changelog update only; no runtime
code changes are included, so functional risk is minimal beyond
publishing the new versions.
> 
> **Overview**
> Bumps the monorepo release to `88.0.0` and publishes new versions of
`@metamask/hw-wallet-sdk` (`0.5.0`) and `@metamask/keyring-api`
(`21.5.0`).
> 
> Changelogs are updated to reflect the releases, including
`hw-wallet-sdk` Ledger status-code error mapping fixes/additions and
`keyring-api` updates that add stricter ETH address types/helpers while
reverting an unintended address-type breaking change and marking
`21.4.0` as *deprecated* (instead of yanked).

   - Changes in [#405](https://github.com/MetaMask/accounts/pull/405) updated the associated type for `EthAddressStruct` from `string` to `Hex`, this was actually a small breaking change that went unnoticed and that would require some effort to adapt in upstream clients/controllers, for this reason, we are undoing this change for now.
