CheetahClaws in HarnessRouter

HarnessRouter v0.25.0 adds CheetahClaws 3.5.88 as backend sixteen, driven in process through the upstream agent loop.

Verified: HarnessRouter: v0.25.0+CheetahClaws: 3.5.88

PR #264, released in HarnessRouter v0.25.0, adds CheetahClaws 3.5.88 as the sixteenth base backend.

HarnessRouter drives the upstream agent loop in process rather than scraping terminal output. The driver re-emits live events as NDJSON and keeps provider routing, usage accounting and session recovery inside HarnessRouter’s adapter boundary.

This proves HarnessRouter adapter support for CheetahClaws. It does not establish that the upstream CheetahClaws project natively implements or endorses UHP.

The upstream CLI’s saved session file is not a progressive event stream, so HarnessRouter consumes the agent generator directly for live task events. Provider credentials route through HarnessRouter’s relay rather than being persisted into the CLI state.
