Pro launcher: reach the render farm directly, not through the page's proxy

[JWriter20]

Bug: with a proxy and a farm GPU grant, the browser's render-farm WebSocket goes through the proxy. Camoufox Pro's warm sessions on dev showed it: every browser socket went to the warming proxy (:8081), cfp-render saw zero farm connections from 235 granted warm leases, and render-dev.camoufox.com is unreachable through that proxy (curl exit 56; example.com through the same proxy: 200). The farm route never opened, so heavy canvas/WebGL calls blocked until cfp-warm's 300 s watchdog killed the browser — most of the "browser call stuck after a pause" crashes. On production the same path would send all farm traffic through a customer's (often metered) residential proxy.

Fix (Python and TS): with a gpu grant and a proxy, the render endpoint's host is appended to proxy.bypass, after the caller's own entries. Without a proxy nothing changes.

Tests: both launchers: a farm launch with {server, bypass: "intranet.example"} ends with bypass = "intranet.example,render.example", and without a caller bypass, "render.example". Fail before (bypass unchanged), pass after. TS suite 821 passed, biome + tsc clean; Python suite 651 passed — the one failure, test_geoip_config.py::test_refresh_keeps_an_explicit_choice, fails on feat/pro_integration without this change too.

_{The Playwright suite is upstream playwright-python at the tag above, fetched fresh, with tests/camoufox/ overlaid. It runs with world isolation on — the configuration Camoufox ships — and only the failures are re-run with it off; those count as passes and are reported above as main-world fallbacks, which is the size of the isolated-world gap. Tests Camoufox cannot pass by design are deselected via ci/skiplist.yml — each with a stated reason. The stealth check reports a grade only; its per-vector detail is deliberately never published.}
