Add wasm packages for .net sdk

[jsturtevant]

This makes it easy to consume the wasm guests. Follows same pattern as Python SDK

[Copilot]

Pull request overview

Adds first-class .NET NuGet packages that bundle the prebuilt Wasm/AOT guest modules (Python + JavaScript), matching the “batteries-included guest” consumption pattern used by other SDKs, and updates the .NET examples/docs to use these packages.

Changes:

• Introduces Hyperlight.HyperlightSandbox.Guest.Python and Hyperlight.HyperlightSandbox.Guest.JavaScript packages with WithPythonModule() / WithJavaScriptModule() builder helpers.
• Updates .NET examples and docs to use bundled guest modules instead of manually providing .aot paths.
• Updates the .NET Justfile to build guest artifacts before running examples and packing NuGet packages.

src/wasm_sandbox/guests/javascript/package-lock.json:229

• package-lock.json still references @emnapi/core / @emnapi/runtime (e.g., as peer dependencies of @napi-rs/wasm-runtime), but their node_modules/@emnapi/* entries were removed from the lockfile. This will likely break npm ci / reproducible installs. Regenerate the lockfile with npm install (or ensure the @emnapi/* packages are fully removed from the dependency graph) so the lock includes consistent resolved + integrity metadata.
