Functions
ScopeId	group2::perf::registerScope (const char *name)
	Register (or look up) a scope name and return its dense id.
const char *	group2::perf::scopeName (ScopeId id)
	Returns the human-readable name a ScopeId was registered with, or "" if id is out of range.
std::size_t	group2::perf::scopeCount ()
	Returns the highest registered id + 1.
void	group2::perf::recordSample (ScopeId id, std::uint64_t ticks) noexcept
	Recording entry point — public so unit tests can invoke it directly without a real ScopeTimer.
void	group2::perf::tickEnd (std::uint64_t tickWallNs) noexcept
	Tick boundary marker — call once per server tick() end.
void	group2::perf::initFromEnv ()
	Initialize from environment variables.
void	group2::perf::startAggregator (std::function< void(const Snapshot &)> cb)
	Spawn the 1 Hz aggregator thread.
void	group2::perf::stopAggregator ()
	Stop the aggregator and join its thread. Idempotent.

Variables
std::atomic< bool >	group2::perf::enabled {false}
	Master switch.
