v2.0.0

Added

• Added optional AmbientContextRegistrationAttribute for collision-resistant, assembly-specific aggregate registration methods.
• Added generated I{Name}Context interfaces and synchronous ExecuteAs{Name} overloads.
• Added generator diagnostics for invalid namespaces, open generic values, duplicate or invalid aggregate registration declarations, and generated name collisions.
• Added approved public API snapshots and NuGet package validation.
• Added integration guidance and buildable ASP.NET Core and message-processing samples.

Changed

• Consolidated the public core runtime into AmbientContextRuntime<TContext, TValue>.
• Generated markers, accessors, context implementations, constructors, and registration helpers are now internal.
• Generated dependency injection registration is idempotent.
• Analyzer matching now identifies generated AmbientContext methods semantically.

Removed

• Removed public ValueTask execution overloads in favor of unambiguous Task-based delegates.
• Removed the collision-prone parameterless AddAmbientContext() aggregate methods.
• Removed the unused MAAC0001 analyzer rule.
• Removed the previous public accessor, runner, state, and options infrastructure types.

Fixed

• Updated Forgejo package publishing to use a dedicated package-scoped personal access token and support retrying an existing release tag manually.
• Enabled automatic NuGet.org trusted publishing for release tag pushes while retaining safe manual retries for existing tags.
• Publishing workflows now create idempotent GitHub and Forgejo releases from the matching changelog section after packages are published.
