Migrate threaded WASI loader to napi-rs 3.8 and emnapi v2

[ishiko732]

Summary

• upgrade the binding toolchain to napi-rs 3.12, @napi-rs/cli 3.8, wasm-runtime 1.2, and emnapi v2
• remove the local napi-rs CLI patch and publish a single ESM Node loader requiring Node.js 24+
• rebuild the threaded Node/browser dynamic loaders with initialization rollback, deterministic disposal, and worker cleanup
• expose ./dynamic while preserving ./dynamic-wasi as a same-file compatibility alias
• update build artifacts, tests, documentation, and the changeset

Why

The existing dynamic loaders were based on the older emnapi v1 runtime and no longer matched the lifecycle and plugin contracts generated by napi-rs CLI 3.8. Migrating them together avoids a runtime/loader version mismatch and removes the need to maintain separate CommonJS and ESM Node loaders.

Impact

• @open-spaced-repetition/binding now requires Node.js 24 or newer.
• Existing ./dynamic-wasi consumers continue to work.
• This PR remains limited to native and threaded wasm32-wasip1-threads outputs; threadless WASI and Cloudflare support remain follow-up work.
• The Preview Release workflow can build native Node and threaded WASI artifacts before publishing them with pnpm dlx pkg-pr-new@0.0.79 publish.

Validation

• frozen-lockfile install with Node.js 26
• native release build
• wasm32-wasip1-threads release build
• binding tests: 6 files, 57 tests passed
• Biome, Cargo fmt, Clippy, and Taplo checks
• packed binding imported through ESM and CommonJS on Node.js 24
• git diff --check
