v0.8.0 Performance Validation Examples

The live validation example at adk-rust/examples/performance_0_8_llm_agents.rs runs 12 real LLM agents using provider credentials from the environment or repo .env. Each agent maps one v0.8.0 optimization to a user-friendly adoption scenario and validates the response internally without printing model output:

1. scaffold_advisor validates current cargo-adk templates for a small support bot.
2. install_doctor explains the rustls-only install path for OpenSSL-friction cases.
3. starter_agent validates the true minimal tier for a simple reminder agent.
4. cli_provider_advisor shows provider-specific CLI installs.
5. telemetry_triage separates local tracing from OTLP export.
6. tooling_advisor keeps MCP out of local function-tool agents.
7. gemini_debug_advisor keeps Gemini backtraces debug-only.
8. session_budgeter covers empty state-delta session writes.
9. history_window_support uses RunConfig.history_max_events.
10. privacy_observer caps trace payload bytes.
11. operations_dispatcher uses RunConfig.max_tool_concurrency.
12. cache_operator validates cache lifecycle work that does not hold the cache mutex across network calls.
