Summary:

  • Harden MessagingBridgeGenerator to emit containing partial wrappers for nested hosts.
  • Expand Messaging Bridge generator coverage through TinyBDD xUnit scenarios.
  • Cover defaults, invalid named configuration, malformed type arguments, host type shapes, escaped bridge names, nested accessibility wrappers, and emitted-compilation success.

Coverage:

  • MessagingBridgeGenerator: 98.9% locally.
  • PatternKit.Generators: 95.2% locally.

Validation:

  • Focused MessagingBridgeGeneratorTests passed on net10.0.
  • Full PatternKit.Generators.Tests passed on net8.0, net9.0, and net10.0.
  • Generator coverage run completed with Cobertura plus ReportGenerator summary.
  • dotnet format PatternKit.slnx --verify-no-changes passed.

Closes part of #413.

Pull request overview

This PR expands Messaging Bridge source-generator coverage and updates the generator so nested bridge hosts are emitted inside containing partial wrappers.

Changes:

  • Adds TinyBDD/xUnit scenarios for defaults, diagnostics, malformed type args, nested hosts, escaping, and emitted compilation.
  • Updates MessagingBridgeGenerator to generate wrapper declarations for containing types around nested hosts.
  • Consolidates test compilation/emission assertions through a shared helper record.
