docs(Echo): enhance performance contribution guidelines and roadmap

- Added prominent 'Call for Contributions' section in README with categorized optimization tasks
- Updated TODO.md with detailed performance challenges aligned with Echo's role in Tauri IPC layer
- Structured contribution levels (Quick Wins/Architectural/Expert/Advanced) to guide community involvement

These changes directly support Land's architecture by:
1. Strengthening Echo's scheduler performance critical for Mountain-Wind communication
2. Providing clear pathways to optimize IPC workloads affecting editor responsiveness
3. Aligning with recent scheduler refactors (work-stealing, API exposure) from commit history
4. Maintaining focus on resource efficiency across Rust/TS boundaries

+`Echo` is built on a high-performance foundation, but there's always room to
+push the boundaries of speed and efficiency. We maintain a detailed roadmap of
+features and performance optimizations, with tasks suitable for all skill
+levels.
+
+| Contribution Level | Example Tasks                                               |
+| :----------------- | :---------------------------------------------------------- |
+| **Quick Wins**     | Implement faster random number generation for stealing.     |
+| **Architectural**  | Add a true sleep/notification system for idle workers.      |
+| **Expert Tuning**  | Build a `criterion` benchmark suite; implement CPU pinning. |
+| **Advanced Logic** | Introduce an anti-starvation mechanism for tasks.           |
