chore: create unity project

[ImmutableJeffrey]

Summary

• Adds a minimal Unity project at examples/audience/ for verifying the com.immutable.audience package compiles inside the Unity Editor.
• Manifest references the package via file:../../../src/Packages/Audience, matching the existing examples/passport/ pattern.

Known issue for reviewers

Opening this branch alone in Unity will fail to compile: src/Packages/Audience/Tests/Runtime/Transport/HttpTransportTests.cs:378 uses Assert.DoesNotThrowAsync, which is absent from the NUnit that ships with com.unity.test-framework 1.1.33. Fix will follow in a separate PR. Merge this PR together with or after that fix.

Test plan

• Open examples/audience/ in Unity Hub (Editor version per ProjectSettings/ProjectVersion.txt).
• Confirm package import succeeds and the manifest reference resolves.
• After the NUnit fix merges, verify Console is free of red errors.

Note

Low Risk
Adds Unity project configuration and lockfiles only, with no production code or security-sensitive logic changes; main risk is repo churn/size and Unity version/package pin compatibility.

Overview
Adds a new minimal Unity project scaffold under examples/audience/, including Unity ProjectSettings/Packages configuration and a packages-lock.json, to serve as an editor-level compilation/packaging smoke test environment.

No runtime/package code is changed; this PR primarily introduces Unity-generated settings/assets metadata (input/quality/graphics/audio/etc.) pinned to Unity 2021.3.45f2.

Audience package reference missing from manifest

High Severity

The manifest.json is missing the com.immutable.audience dependency entry. The PR description states the manifest references the package via file:../../../src/Packages/Audience, and the existing examples/passport/ pattern includes "com.immutable.passport": "file:../../../src/Packages/Passport" — but the audience manifest has no such entry. Without it, this example project cannot fulfill its stated purpose of verifying the audience package compiles in the Unity Editor.
