Add CI-runnable HTTP test fixture on the testsrvr/testclnt harness

Drives socket.http.request against fully scripted, controlled raw HTTP
responses over a real socket by reusing the existing testsrvr.lua
remote-execution server -- no Apache, no Docker, no third-party hosts.
Proves the fixture with a plain-GET smoke test, a chunked-transfer-
encoding smoke test, and a test asserting a response body delivered
across separately-timed writes (the incremental-delivery capability the
upcoming SSE tests need). Wires the new test into the CI regression step.
