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

- @pezkuwi/dev, dev-test, dev-ts ^0.86.3; disable directives renamed
  for the new rule names, or removed where the rule no longer reports
- rethrown errors carry the original as `cause` (13 sites)
- optional chains where a guard expression tested the same value
- Init: the registry cache settles with the creator's own promise,
  dropping the entry in finally(), instead of re-wrapping it
- Combinator: a typed call instead of `Function`
- checkTypes.manual: synchronous checks run outside Promise.all
- sortValues, createTypeUnsafe: initial values that were never read
- typegen util: load docs.js for its side effect (it registers the
  `docs` Handlebars partial) now that its types are re-exported
  type-only
- MockProvider keeps its Header assertion: the package's own build
  does not load api-augment, so createType returns a plain Codec there
- Decorate keeps `delete queue[i]`: the hole marks a fired queue and
  later indexes must not shift
