  "message": "[HAL] Add command buffer flush and invalidate operations (#24945)\n\nThis PR adds HAL and runtime plumbing for ordered command-buffer buffer\nflush and invalidate operations.\n\nIt introduces:\n\n* `hal.command_buffer.flush_buffer`\n* `hal.command_buffer.invalidate_buffer`\n* HAL-to-VM lowering and VM imports\n* runtime command-buffer API and vtable hooks\n* VM module/shim plumbing\n* inline command-buffer support\n* deferred command-buffer recording/replay support\n* HAL IR and HAL-to-VM test coverage\n\nThe operations carry a buffer reference, offset, and length and are\nintended to represent execution-ordered cache maintenance for shared\nnon-coherent memory.\n\nStream-to-HAL lowering is intentionally left unchanged in this PR. Some\nbackends, especially Vulkan, require queue/submission-level handling to\npreserve execution-time ordering because a HAL command buffer is\ncurrently replayed into a single native `VkCommandBuffer`. Enabling\nStream lowering before that backend support exists could cause\nunsupported runtime paths.\n\nThis PR therefore focuses on establishing the HAL/runtime infrastructure\nfirst. Backend-specific execution support and Stream lowering can follow\nseparately.\n\nRelated to #24930.\n\nAI Tool Disclosure\nAssisted by codex for code base exploration\n\nSigned-off-by: purnima \u003cpurnima.shrivastava@sandlogic.com\u003e",
