fix: allow npm install without changing yarn-first workflow

[JackWilb]

Closes #1218

Summary

Allow habitual npm install users to install dependencies without changing the project's Yarn-first workflow.

Changes

• package.json: remove the Yarn-only preinstall guard that hard-failed npm installs.
• package.json: align lint dependencies for npm peer resolution by downgrading eslint to ^8.57.1 and eslint-plugin-react-hooks to ^4.6.2 while keeping the Airbnb-based lint setup intact.
• package.json: update @visdesignlab/upset2-react to ^1.2.4, react-vega to ^8.0.0, and vega-lite to ^6.0.1 so strict npm peer resolution succeeds.
• yarn.lock: refresh the Yarn lockfile to reflect the dependency updates.
• package-lock.json: add an npm lockfile generated from the updated dependency graph.

Validation

• yarn install --mode=skip-build
• npm install --package-lock-only --ignore-scripts
• yarn typecheck (currently fails on pre-existing errors in src/store/hooks/tests/usePreviousStep.spec.ts)
