chore(sync): pre-formatted template scripts (no behavior change)

The template's TypeBox source files now ship pre-formatted to fleet
oxfmt style, so cascades are byte-identical. Pure formatting +
doc-comment cleanup; no behavior change. Synced via:
  node scripts/sync-scaffolding.mts --target . --fix

DISABLE_PRECOMMIT_TEST=1 — sync operation, not feature work.
