Bump Feather Wand 3.8.8

[QAInsights]

What's new

• New Decisions backends for smart routing and failure triage. jmeter.ai.judgment.provider now accepts openai (OpenAI Decisions API uses openai.api.key and openai.decisions.model, default gpt-6-luna) and openrouter (OpenRouter Decisions API uses openrouter.api.key, default microsoft/microsoft-decision-1), alongside the default typesafe (Jev). OpenRouter cards name the model vendor, e.g. "Microsoft Decision".
• Actionable provider errors. Agent Mode surfaces the provider's real error message instead of a generic apology.
• Richer anonymous telemetry. The daily anonymous ping now also counts agent outcomes, tool calls, routing/triage judgments and provider errors, and reports the configured Decisions backend and well-known model. The telemetry worker adds retention stats, version adoption, Java/arch/agent/model/Decisions breakdowns and grouped feature tables.

Improvements and fixes

• Jev stays silent when typesafe.api.key is missing or still the placeholder no more "Jev unavailable" Smart Route card on every Agent Mode reply.
• CSV import rejects invalid shareMode values; chat questions are no longer fed to the element parser.
• Triage advisories sent to the model are labeled with the active backend; the agent logs why routing/triage judgments are unavailable.
