Commit Message

core: harden setDataAt/unsetDataAt against edge cases

Improvements on top of the lodash/fp/set replacement:

- Store "__proto__" segments as own properties via defineProperty and
  traverse own properties only, so such keys neither corrupt the
  container's prototype nor get dropped. Clone containers key-by-key
  because downleveled object spreads assign instead of define.
- Read the updater's old data with resolveData instead of lodash get,
  so reads use the same literal path semantics as writes.
- Fall back to lodash's index heuristic when creating missing
  containers without schema type information.
- Match lodash's isIndex semantics with a strict index regex instead
  of Number() coercion.
- Avoid strict-mode TypeErrors when unsetting non-index array
  properties (e.g. "length") and return the same reference when
  there is nothing to unset.
- Treat an empty path as addressing the root, and replace non-object
  root data instead of spreading it.

Also documents the path semantics change in MIGRATION.md and adds unit
tests for setDataAt/unsetDataAt.
