<h3>Summary</h3>

- This PR reworks `nescapture` frame capture around a four-slot DMA-BUF
ring, tracks presentation queue families, adds semaphore-based
capture/present ordering, introduces capture frame-rate pacing, carries
presentation timestamps through encoding, and updates Vulkan-related
dependencies.
