📝 Walkthrough

Walkthrough

This PR updates the project to support React 19 while maintaining backwards compatibility with React 18. Root-level dependency overrides pin React 19.0.0, core package version ranges widen to accept both v18 and v19, and Docker build configuration is enhanced with linux-headers and lock file cleanup.

Changes

Cohort / File(s)	Summary
Docker Build Configuration apps/demo/Dockerfile	Added linux-headers to apk dependencies for native module compilation and removed bun.lock before running bun install to ensure fresh dependency resolution with overrides applied.
Root Dependency Overrides package.json	Added top-level "overrides" field pinning react and react-dom to version 19.0.0 to control transitive dependency resolution.
Core Package React Compatibility packages/core/package.json	Expanded react, react-dom, @types/react, and @types/react-dom version ranges from "^18.0.0" to "^18.0.0 || ^19.0.0" to support both major versions.

Poem

🐰 A rabbit hops through version lanes,
React 18 and 19 now both remain,
Dependencies aligned so bright,
Compatibility takes its flight!
With headers built and overrides set,
The future's ours—no need to fret! 🚀
