vii c6c354fdb1 perf(graphics): emit ETC2 uploads on the decode pool and stop the trace writer after a failed write 
EmitPass reuses the decoder's persistent workers through RunOnDecodeWorkers
instead of creating and joining threads per batch. A failed trace write stops
the writer thread rather than leaving it ticking every 250 ms.

vii 88d10d53f2 perf(graphics): decode ETC2 uploads off mapped memory on worker threads 
Compressed bytes are copied to heap scratch, decoded heap to heap across
up to 8 threads in block-row bands, and streamed into the staging buffer.
Decoding straight from uncached Vulkan memory caused 200-460 ms hitches.
The FPS trace now reports the longest frame gap per window.

vii eae9fa7030 feat(graphics): emulate ETC2/EAC textures on Vulkan 
Hosts without native ETC2 now report ETC2/EAC support. Uploads into emulated images are decoded to RGBA8/R16 staging buffers at submit. MOCKTAIL_DISABLE_ETC2_EMULATION=1 turns it off.
