java headers are generated and enforced by spotless licenseHeader from
the root copyright file; the typescript surfaces had no such control -
dc3-cli carried zero headers across 32 files and dc3-web was missing
one hand-written file:
- add scripts/add-license-header.mjs (shared by both packages) that
reads the same root copyright and emits block comments for ts and
html-comment headers for vue, with a --check mode for ci
- wire headers / headers:check npm scripts; unplugin-generated ambient
d.ts files are exempt (the generator owns their file head)
- backfill all 32 dc3-cli sources and operation.ts / type.d.ts
verified: headers:check green on both packages, cli 67/67 tests +
build + lint, web 687/687 tests + lint + format
