chore: bump renderers to 0.1.9

[hallerite]

Bumps renderers to the first stable release since 0.1.8 (>=0.1.9.dev9 → >=0.1.9), dropping the dev-version pin from #2175.

0.1.9 is a patch release: client fixes (vLLM token serving import, malformed sampled-token evidence rejection), GLM tool-name validation, Qwen empty-think-wrapper retention, and a bridge-merge multi_modal_data mutation fix.

Note

Low Risk
Dependency version pin and lockfile update only; no application logic changes in this PR.

Overview
Pins the core renderers dependency from the pre-release floor >=0.1.9.dev9 to the stable release >=0.1.9, and refreshes uv.lock so the resolved package is renderers 0.1.9 (new sdist/wheel hashes).

This is a dependency-only change: consumers pick up the published 0.1.9 renderer stack (client/tooling fixes in that release) without changing verifiers application code in this diff.
