Needed to measure steady-state frame throughput without the compositor's vblank cap; FIFO remains the default when the variable is unset.

test(bench): SponzaBench harness + #40→HEAD perf measurement (#155 )

Headless benchmark around the native Sponza RT scene: times setup and a
measured Render() loop over the full multi-mesh atrium, prints BENCH
metrics, and exits. Includes run-bench.sh and a README documenting the
methodology and the measured net gain from #40 to current master.

feat(window): env-gated uncapped present mode for benchmarking

CRAFTER_PRESENT_IMMEDIATE selects IMMEDIATE (then MAILBOX) when the
surface offers it, instead of the default FIFO. Needed to measure
steady-state frame throughput without the compositor's vblank cap; FIFO
remains the default when the variable is unset.
