[repowarden-app]

Summary

This PR consolidates and supersedes 8 open Dependabot PRs by updating development dependencies, build tools, and GitHub Actions to their latest versions. The updates include significant improvements to the TypeScript/SWC toolchain, testing utilities, and CI/CD infrastructure.

Changes

Dependencies Updated

• @swc/core: 1.3.42 → 1.15.47 (major version bump)
• @swc/jest: 0.2.24 → 0.2.39 (minor update)
• @testing-library/jest-dom: 5.16.5 → 5.17.0 (patch)
• @types/react: 18.0.28 → 18.3.31 (minor)
• eslint-import-resolver-typescript: 4.4.4 → 4.4.5 (patch)
• plyr: 3.7.7 → 3.8.4 (minor) - peer dependency for this library
• tsdown: 0.2.0 → 0.22.14 (major version bump)
• typescript: 5.0.4 → 5.9.3 (minor)
• typescript-eslint: 8.41.0 → 8.66.0 (patch)
• prettier: 3.6.2 → 3.7.4 (minor)

GitHub Actions Updated

• actions/checkout: 3.6.0 → 6.0.2
• actions/setup-node: 3.9.1 → 6.3.0
• actions/upload-artifact: 4.6.2 → 6.0.0
• actions/dependency-review-action: 4.7.3 → 4.8.2
• step-security/harden-runner: 2.14.0 → 2.17.0

Risk Assessment

Risk Level: MEDIUM

• @swc/core and tsdown major version bumps may introduce breaking changes in build behavior
• TypeScript and typescript-eslint updates are within compatible ranges
• No security vulnerabilities identified
• This is a library project—updates should be validated against all target Node.js LTS versions (18, 20, 22)

Action Items

• Verify tsdown 0.22.14 build output matches expected format
• Test against Node.js 18, 20, and 22 LTS versions
• Confirm @swc/core 1.15.47 doesn't affect transpilation output
• Review plyr peer dependency compatibility (3.8.4) with consuming applications
• Validate ESLint configuration with typescript-eslint 8.66.0
• Run full test suite including integration tests
• Check that peer dependency ranges in package.json remain appropriate

Testing Recommendations

• npm ci && npm run build on all target Node.js versions
• npm run test - full test suite
• npm run lint - verify ESLint still works correctly
• npm run type-check - ensure TypeScript compilation succeeds
• Manual smoke test of library functionality with a sample consumer app
• Verify generated bundle sizes haven't regressed significantly
