Some false positives & missing suggestions

## Missing suggestions:
legend: `misspelling` -> `what I meant but wasn't in the suggestion list`
- `runing` -> `ruining` (e.g. it is ruining my life)
- `re-inforces` -> `reinforces` (only `inforces` was underlined)

## False positives
real words which were underlined as not recognized
- [animalistic](https://www.wordnik.com/words/animalistic)
- [supernormal](https://www.wordnik.com/words/supernormal)

using US Dialect.

No file or test is named in the issue. Start by reproducing the US-dialect cases for “runing”, “re-inforces”, “animalistic”, and “supernormal” in Harper, then trace the checker’s suggestion and word-recognition behavior. Done means the intended suggestions appear and the listed real words are no longer flagged.
