The Android develop view reads its frame back through memory (TD-1) because wgpu's Vulkan swapchain never pre-rotates, and a portrait window on this tablet's landscape panel then tears. The fix is a small patch to each of these two crates, and this commit is only the ground it lands on: both are byte-for-byte the crates.io sources the lockfile already resolved, so the commits that follow are the patch and nothing else. third_party/ is excluded from the workspace, or every path dependency under the root would become a member and `--workspace` would test and lint upstream code as ours. The README says how to carry the patches across a Slint or wgpu bump, which matters because a stale version here does not fail the build — cargo just warns and uses the unpatched crate.
