Move to @pezkuwi/dev 0.86 (eslint 10 toolchain)

- @pezkuwi/dev, dev-test, dev-ts ^0.86.3
- rethrown errors carry the original as `cause` (hw-ledger, address decode)
- optional chain in isEthereumAddress, includes() in bip39 validation
- logger calls the lazy formatter through a typed function
- x-global: an assertion to the type the value already has removed,
  with the comment and directive that explained it
- type-only re-exports of modules that emit no JavaScript
- disable directives renamed for the new rule names, or removed where
  the rule no longer reports
