Default renderer logLevel to 'info'

Pro docs (docs/oss/building-features/node-renderer/container-deployment.md)
prescribe `logLevel: 'info'` as the general-renderer-logs default, and
the Pro dummy's renderer/node-renderer.js also uses 'info'. The inherited
'debug' default is too verbose for normal operation (emits the full VM
context setup messages like "Adding Buffer, TextDecoder, ...").

Debug remains reachable via RENDERER_LOG_LEVEL=debug env var as docs
describe for active debugging (docs/oss/building-features/node-renderer/
debugging.md).
