style: cargo fmt --all (round 4 ingest log feature follow-up)

Phase C4 executor 의 마지막 `fix(test): clippy + fmt fixes` commit 이
test file 부분만 fmt 적용. workspace 전체 fmt 누락 발견 → cargo fmt --all
적용. 모든 import alphabetical reorder + line wrapping 정합.

- docs/superpowers/specs/2026-05-28-v0.20-ingest-log-spec.md (491 line, ACCEPT)
- docs/superpowers/plans/2026-05-28-v0.20-ingest-log-plan.md (616 line, ACCEPT)
