What changed in this PR
Preserves important A2A task-status messages in .NET agent responses instead of discarding failure explanations and other actionable content.
Changes:
- Applies shared status-message conversion across ordinary and streaming responses.
- Continues omitting routine progress and successful-completion messages.
- Adds regression coverage for status filtering, artifacts, and continuation behavior.
