feat(completion): replace orderless with fussy

Use fussy instead of orderless for filtering and scoring/ordering
completion candidates. This seems to overall order results in a much
better way than just orderless.

Technically orderless is still used to filter the candidate list, but
fzf-native is used to score/order the results.
