chore(deps): update @napi-rs/cli and emnapi, group emnapi in renovate

[Brooooooklyn]

Changes

Package	Before	After
@napi-rs/cli	^3.8.6	^3.9.1
@emnapi/core	^2.0.0-alpha.4	^2.0.0-alpha.5
@emnapi/runtime	^2.0.0-alpha.4	^2.0.0-alpha.5
emnapi	^2.0.0-alpha.4	^2.0.0-alpha.5

• example/index.d.ts is re-generated with CLI 3.9.1 (one blank line after the header).
• .github/renovate.json groups emnapi and @emnapi/** into one Renovate PR.

Why

Renovate PRs #95 and #96 said they updated @emnapi/* to alpha.5. They only changed the transitive ^1.5.0 lockfile entries. The direct deps stayed at 2.0.0-alpha.4.

Verification

• yarn install resolved the four deps to the new versions
• yarn build (native) passes
• yarn build --target wasm32-wasip1-threads passes with emnapi 2.0.0-alpha.5
• renovate-config-validator reports the config is valid
• yarn install --immutable passes

Note

Low Risk
Example-only devDependency and lockfile updates plus Renovate grouping; no runtime or security-sensitive application logic changes.

Overview
Bumps the example NAPI/WASM toolchain so direct devDependencies match the intended emnapi 2.0.0-alpha.5 line and @napi-rs/cli ^3.9.1, with example/yarn.lock refreshed (including transitive bumps such as @emnapi/wasi-threads and js-yaml from the CLI).

Adds a Renovate packageRules group named emnapi for emnapi and @emnapi/** so future emnapi-related updates land in one PR. Regenerates example/index.d.ts via the newer CLI (cosmetic blank line after the header).
