refactor: Store const GpuContext& in Effect base class

- Changed Effect to store ctx_ reference instead of device_/queue_/format_
- Updated all 19 effect implementations to access ctx_.device/queue/format
- Simplified Effect constructor: ctx_(ctx) vs device_(ctx.device), queue_(ctx.queue), format_(ctx.format)
- All 28 tests pass, all targets build successfully
