chore(deps): update build tools and dependencies

[repowarden-app]

Summary

This PR updates 8 development and peer dependencies, including TypeScript, build tools (@swc), testing libraries, and the peer dependency plyr. All updates are non-breaking minor/patch versions.

Changes

Build & Development Tools

• @swc/core: 1.3.42 → 1.15.33 (multiple minor versions)
• @swc/jest: 0.2.24 → 0.2.39
• tsdown: 0.2.0 → 0.22.0 (significant minor update)
• typescript: 5.0.4 → 5.9.3
• typescript-eslint: 8.41.0 → 8.59.2

Testing Libraries

• @testing-library/jest-dom: 5.16.5 → 5.17.0
• @types/react: 18.0.28 → 18.3.28

Peer Dependencies

• plyr: 3.7.7 → 3.8.4 (minor update with potential features/fixes)

Risk Assessment

Risk Level: Medium

• Most updates are patch/minor versions within the same major version
• TypeScript 5.0.4 → 5.9.3 may introduce stricter type checking
• @swc/core has significant version jump (1.3 → 1.15) that could affect build output
• tsdown 0.2.0 → 0.22.0 is a substantial minor update
• As a library, these changes affect the build process and may impact the distributed package

Action Items

• Review tsconfig.json for any new TypeScript 5.9 options or deprecation warnings
• Verify the library builds successfully with updated @swc/core and tsdown
• Check that type definitions are correctly generated
• Review if plyr peer dependency range in package.json should be updated to ^3.8.4

Testing Recommendations

As this is a library, please test thoroughly:

• Run full test suite: npm test
• Verify builds complete without errors: npm run build
• Test on all target Node.js LTS versions: 18, 20, 22
• Verify type checking passes: npm run type-check (if available)
• Test the library in a consuming application with React 17
• Verify bundled output size hasn't changed significantly
• Check that generated .d.ts files are valid
