Summary

• bump the project tooling to newer majors (TypeScript 5, Vite 5, updated ESLint/Jest suites) and realign dependency ranges while moving build-time packages to devDependencies
• regenerate the lock manifest to capture the refreshed semver targets for both runtime and dev-only packages
• replace the Popper.js-based tooltip with a Solid-driven positioning helper that removes the legacy dependency and keeps placement options intact
• convert the devtools extension detection in App to @ts-expect-error directives so the lint rule acknowledges the intentional suppression

Testing

• npm run typecheck
• npm run lint
• npm run build
