## Summary
- Upgrades `@napi-rs/cli` from v2 to v3, `napi`/`napi-derive` Rust
crates to 3.x
- Fixes a bug
([napi-rs#1170](https://github.com/napi-rs/napi-rs/issues/1170)) where
the CLI failed to locate the built `.node` binary when a custom Cargo
target directory is set (via `config.toml`)
## Changes
**package.json / CLI**:
- `napi.name` → `napi.binaryName`, `napi.triples` → `napi.targets`
- Removed `--no-const-enum` flag and fixed output dir arg
- `napi universal` → `napi universalize`
**Rust API migration**:
- `#[napi::module_init]` → `#[napi_derive::module_init]`
- `napi::JsObject` → `Object`, `.get::<_, T>()` → `.get::<T>()`
- `ErrorStrategy` removed; `ThreadsafeFunction` now takes an explicit
`Return` type with `CalleeHandled = false` const generic
- `JsFunction` + `create_threadsafe_function` replaced by typed
`Function<Args, Return>` + `build_threadsafe_function().build()`
- `RerankerCallbacks` struct removed (`Function<'env,...>` can't be
stored in structs); `VectorQuery::rerank` now accepts the function
directly
- `ClassInstance::clone()` now returns `ClassInstance`, fixed with
explicit deref
- `Vec<u8>` in `#[napi(object)]` now maps to `Array<number>` in v3;
changed to `Buffer` to preserve the TypeScript `Buffer` type
**TypeScript**:
- `inner.rerank({ rerankHybrid: async (_, args) => ... })` →
`inner.rerank(async (args) => ...)`
- Header provider callback wrapped in `async` to match stricter typed
constructor signature

BREAKING CHANGE: removes `aws`, `dynamodb`, `azure`, `gcs`, `oss`,
`huggingface` from default Rust features. They can be enabled by users
as needed.
They are still enabled for Python and NodeJS, since those users don't
control the compilation of artifacts.
Closes#2911
