separate out renderer crate (#13)

* add keyboard handler * some cleanup * add l key binding * Fix WASM shared memory generation for Rust nightly 2025-10-20+ Add explicit linker flags for shared memory generation after Rust PR #147225 removed automatic flags with +atomics. This fixes DataCloneError when sharing memory with workers. Changes: - Add --shared-memory, --max-memory, --import-memory flags - Export TLS symbols: __wasm_init_tls, __tls_size, __tls_align, __tls_base - Update both Cargo.toml and package.json build scripts Amp-Thread-ID: https://ampcode.com/threads/T-41d99b69-5754-4fdf-b06e-a46343fa7485 Co-authored-by: Amp <amp@ampcode.com> * add a level-editor crate * remove redundant worker setup * simplify app setup * add SceneBuilder * separate out default scene implementation in a crate * define default method for MeshBuilder --------- Co-authored-by: Amp <amp@ampcode.com>
