chore(deps): update build tooling and dependencies across the board

[repowarden-app]

Summary

This PR updates 8 dependencies including build tools, TypeScript toolchain, testing utilities, and the core plyr peer dependency. All updates are non-breaking minor or patch versions.

Changes

Build & Compilation Tools

• @swc/core: 1.3.42 → 1.15.33 (minor bump with performance improvements)
• @swc/jest: 0.2.24 → 0.2.39 (minor updates)
• tsdown: 0.2.0 → 0.22.0 (significant minor version jump)
• typescript: 5.0.4 → 5.9.3 (minor updates with new language features)

Linting & Code Quality

• typescript-eslint: 8.41.0 → 8.59.3 (patch updates)

Testing

• @testing-library/jest-dom: 5.16.5 → 5.17.0 (minor update)

Type Definitions

• @types/react: 18.0.28 → 18.3.28 (patch updates for React 18 types)

Core Dependencies

• plyr: 3.7.7 → 3.8.4 (minor update to the underlying player library)

Risk Assessment

Risk Level: Medium

• TypeScript 5.9.3 includes new compiler features and stricter checks that may surface type errors
• tsdown jumped from 0.2.0 to 0.22.0, which could affect the build output
• plyr 3.8.x is a minor update but as a core dependency warrants thorough testing
• SWC updates are substantial but typically backward compatible
• Most other changes are patch-level updates with low risk

Testing Recommendations

• Verify the library builds successfully without TypeScript errors
• Run the full test suite and ensure all tests pass
• Test the built library against all target Node.js LTS versions (18, 20, 22)
• Verify the library works correctly when consumed in a React application
• Check that the bundled output size hasn't significantly increased
• Test core Plyr functionality (play, pause, seek, volume control) in example app
• Verify TypeScript definitions are correctly exported for consumers
• Review any new TypeScript compiler warnings/errors that may surface
• Confirm compatibility with React 17.0.2 (current version)

Additional Notes

Overlapping Dependabot PRs

The following open Dependabot PRs can likely be closed after merging this consolidated update:

• build(deps-dev): bump prettier from 3.6.2 to 3.7.4 #1238: Prettier update (not included here, can remain separate)
• Other PRs appear to be GitHub Actions updates and should remain separate

Action Items

• Review tsconfig.json to ensure it's compatible with TypeScript 5.9.3
• Consider updating the engines field if Node.js 16 is EOL (currently >=16)
• Peer dependency ranges should be reviewed to ensure plyr 3.8.x is acceptable
