style: gofmt all packages (#4)

Applies gofmt to the 18 files that were already unformatted at HEAD (pre-existing debt — 122 insertions / 122 deletions, whitespace plus import-block reorderings only; `git diff -w` confirms no semantic changes).

Kept on its own branch so the functional change set (see the review-hardening PR) stays reviewable without formatting noise.

Verified: go build, go vet, go test ./... pass on this branch; a merge simulation with the functional branch produces a clean 3-way merge with all tests green.
Reviewed-on: #4
