refactor: migrated native tools to WASM-based implementation

- Consolidated grep, find, and image processing into a new `@oh-my-pi/pi-natives` WASM package.
- Eliminated subprocess overhead and simplified JS tool implementations.
- Updated CI to include Rust workspace, linting, formatting, and WASM build steps.
- Documented `Promise.withResolvers()` and `using` declarations for wasm-bindgen.
