Add run-tests.sh unified test runner; register log-info/log-warn as PRIMITIVES

run-tests.sh runs all suites: JS (standard + full), Python, OCaml,
Playwright (isomorphic + demos). deploy.sh calls it as gate.

Register log-info and log-warn as PRIMITIVES so runtime-eval'd SX code
(init-client.sx.txt) can use them.
