#5 Update dependabot.yml

Summary by cubic

Normalizes whitespace and end-of-file formatting across config and workflow files to reduce noisy diffs. No behavior changes to builds, workflow triggers, TypeScript config, or Dependabot schedule (still weekly on Monday).

• Changes limited to .editorconfig, .github/dependabot.yml, .github/workflows/provenance.yml, .config/tsconfig.rollup.json, and .dep-stats.json (trailing spaces/blank lines/newline-at-EOF only).
• No action required.
