Detect the OMNIGENT environment variable and report meta-harness/omnigent as an independent user-agent dimension, parallel to agent detection. This lets the platform see both the meta-harness (omnigent) and the underlying coding agent (e.g. claude-code) in the same request.

Why
Omnigent is a meta-harness that orchestrates AI coding agents (Claude Code, Codex, Cursor, and others). It is not itself an agent, so it does not belong in the existing
agent/<name>user-agent dimension. We want telemetry that surfaces both the meta-harness and the underlying agent at the same time. ("meta-harness" matches omnigent's own self-description; "harness" alone is how the field labels the underlying agents like Claude Code.)Changes
Before: the SDK reported only
agent/<name>(e.g.agent/claude-code) for the detected AI coding agent.Now: the SDK also reports an independent
meta-harness/<name>dimension. When theOMNIGENTenvironment variable is present (omnigent stampsOMNIGENT=1into every agent process, see omnigent-ai/omnigent#656), the user agent gains ameta-harness/omnigentsegment. Because it is a separate dimension from agent detection, running Claude Code under omnigent yields bothagent/claude-codeandmeta-harness/omnigent, and omnigent never trips the agent "multiple" logic.Implementation mirrors the existing agent dimension, all in
databricks/sdk/useragent.py:META_HARNESS_KEY, a_KNOWN_META_HARNESSEStable, and a presence-basedmeta_harness_provider()(cached for the process lifetime).to_string()appends themeta-harness/<name>segment right after the agent segment.Test plan
