/**
 * Stdout discipline for `scai mcp serve`.
 *
 * The stdio transport reserves stdout exclusively for JSON-RPC frames.
 * Anything else that lands there breaks the protocol. The library code
 * under scai is generally well-behaved (consola defaults to stderr,
 * spinners and the Logger respect SITECOREAI_QUIET/JSON), but
 * `installMcpStdoutDiscipline()` is the belt-and-braces guard:
 *
 *  1. Sets `SITECOREAI_MCP_SERVE=1`, `SITECOREAI_JSON=1`,
 *     `SITECOREAI_QUIET=1`, `SITECOREAI_NON_INTERACTIVE=1` BEFORE any
 *     other scai module loads. These suppress spinners, banners, and
 *     stdout JSON dumps in the existing task runners.
 *  2. Honors `--no-telemetry`: when telemetry is disabled for the
 *     session it sets `SITECOREAI_TELEMETRY=false`. Otherwise it leaves
 *     the env var untouched so normal resolution applies — telemetry is
 *     on by default and `DO_NOT_TRACK` still wins.
 *  3. Installs a consola reporter that pipes every log line to stderr,
 *     regardless of consola's default level/destination behaviour.
 *
 * Call this at the very top of the `mcp serve` command action, before
 * importing any other scai-internal module that might write to stdout
 * during initialization.
