// Name → target lookup for the parser fuzz lane (#1414).
//
// Resolves the real parser targets plus the broken-on-purpose self-check targets, which is the
// only place the two lists meet. The worker resolves targets by name (a target cannot cross a
// worker boundary as a value), so this lookup is what lets self-check cases run in the same
// worker/watchdog path as real ones.
