implement agent reliability features from ADK

[peterj]

Adds reliability features toagents and ModelConfig.

Agent CRD has the reliability field with the following config:

• toolRetries (1–10): reflect-and-retry on failed tool calls — the runtime injects structured reflection guidance into the model context so the agent can self-correct instead of repeating the same failing call
• maxLLMCalls (≥1): cost safety rail capping model calls per request; the run stops with a clear error instead of looping (runtime default 500)
• debugLogging: verbose logging of every LLM request/response and tool call to the agent pod logs (off by default)

ModelConfig retry field:

• attempts (0–20): automatic retries of failed LLM HTTP requests (429/408/5xx) with exponential backoff via the provider SDK. Supported for OpenAI, Azure OpenAI, Anthropic, and Gemini; other providers log a warning

UI is updated to show the settings in the advanced section:

Pull request overview

This PR adds end-to-end “reliability” and “retry” configuration across CRDs, translators, runtimes (Python + Go), and UI so operators can control tool-call self-healing, model-call caps, debug logging, and provider SDK HTTP retry behavior.

Changes:

• Adds spec.declarative.reliability to Agent/SandboxAgent (tool retries, max model calls, debug logging) and wires it through translators into runtime config.
• Adds spec.retry.attempts to ModelConfig and maps it to max_retries in generated runtime config, including provider-specific wiring and warnings for unsupported providers.
• Updates UI forms to expose these settings under an Advanced section; adds unit/golden test coverage for the new plumbing.
