/**
 * Startup notices — stderr only.
 *
 * This server speaks JSON-RPC over stdout. Anything on stdout that is not a
 * protocol message corrupts the stream for every client, so every notice here
 * goes to stderr. `src/__tests__/stdout-purity.test.ts` spawns the built server
 * and proves stdout stays clean up to the first protocol message.
 *
 * Both notices print once per process. There is deliberately no sentinel file:
 * these exist to be discovered, and a sentinel hides them from the operator who
 * has not acted on them yet. `SERVICIALO_QUIET=true` silences both — and only
 * these two. The mode banner and the first-run telemetry notice keep their
 * existing behavior; a patch release does not redefine existing output.
