// tools/register_manifest.cpp — ad-hoc helper for Phase 03 A2 empirical test.
//
// NOT shipped in the installer (warning 2 resolution — option (a)). Registers
// the passed-in absolute manifest path with SteamVR via
// IVRApplications::AddApplicationManifest(path, temporary=false), then enables
// auto-launch for the bigscreen.micmap app key, then exits. Throwaway target —
// delete after Phase 03 exit.
//
// Usage:
//   register_manifest.exe <absolute-path-to.vrmanifest>
//
// Exit codes:
//   0 — manifest registered + autolaunch enabled successfully
//   1 — VR_Init / AddApplicationManifest / SetApplicationAutoLaunch failed
//   2 — usage error
//
// Logging routes through micmap::common::Logger (default ConsoleLogger;
// constructed at static-init time — no init call required).
