Alem Tuzlak f57151990f fix(showcase/ms-agent-dotnet): wire system prompts to Instructions + demo repairs ...

Root cause across nearly every ChatClientAgent: system prompts were passed as
`description:` (agent metadata) instead of `instructions:` (the actual system
message). ChatClientAgent(instructions, name, description, …) therefore ran
with null instructions, so models ignored tool guidance and BYOC JSON demos
emitted prose.

Fixes reported staging failures:
- shared-state-read-write pills: instructions now reach the model + stronger set_notes guidance
- declarative-hashbrown / declarative-json-render: instructions + ChatResponseFormat.Json (LGP parity)
- declarative-gen-ui: catalog-specific design prompt (no DashboardCard), stronger outer agent
- shared-state-streaming: feature was demo-only in the manifest → shell "Backend fixture unavailable"; added to features

Verified: unit suite 79/79 in Docker SDK 9.
