test(pipeline): cover pipeline-cache header validation (#69)

Browse source 
PipelineCacheValidation drives Device::PipelineCacheDataCompatible
directly (no GPU): synthetic device identities + 32-byte cache headers
assert that a matching header is accepted while foreign vendor/device,
a bumped UUID (driver update), unknown version, undersized headerSize,
and short/empty blobs are all rejected. Mirrors the GPU-free style of
MemoryTypeFallback / UploadStrategy. Also gitignore the serialized
pipeline_cache.bin a real-device test run drops in the working dir.

// Issue #69: the engine feeds one shared Device::pipelineCache to every
// vkCreate*Pipelines call and persists it across runs, discarding an
// on-disk blob whose header doesn't match the current GPU. That gate —
// Device::PipelineCacheDataCompatible — is pure logic over the standard
// VkPipelineCache header and Device::deviceProperties, so this test
// stamps synthetic device identities + headers and drives it directly,
// no GPU device needed at runtime.
