Merge main: fix(macos): make Dock Quit cancelable; test(recovery): make failed republishing fixtures deterministic

Conflict: Cargo.toml: next's winit patch (rust-windowing/winit#4694, Windows mixed-DPI drags) kept; main's skylartaylor/winit patch held back (Cargo takes one patch per crate; both are single commits on v0.30.13 for different platforms, no published commit has both)
Conflict: Cargo.lock: next's winit source; main's ui-egui tempfile dev-dependency taken
Conflict: apps/designcraft/src/main.rs: next's startup; main's macOS with_close_requested_on_terminate block left out (needs main's winit patch); apps/designcraft/Cargo.toml keeps next's (no macOS winit dependency)
Conflict: ROADMAP.md: headers combined, logs both
Conflict: docs/target-app-parity.md: headers combined

 - Native engine saves, Save a Copy, snippets, books, libraries, swatches and engine/MCP exports use same-folder atomic replacement, as do desktop Services writes and CLI raster exports. Failed writes before replacement retain the original; existing Unix permissions apply before staging document bytes, and already-open readers retain the old bytes. Parent-folder flushing is best effort, so this is not a power-loss durability guarantee.
 - Save As prepares destination-relative data-source paths before writing and installs them only after a successful save. Failed Save As retains the document, saved state and history; Save a Copy rebases only the saved copy. Library and book collection edits likewise update live values only after persistence succeeds.
 - Crash recovery: unsaved documents are written every 30 s into a locked folder owned by that running app and reopened (unsaved, remembering their files) after a crash. Startup takes entries from ended runs and leaves live runs alone; writes and cleanup validate current folder and lock ownership. Failed isolation disables recovery with a warning. Recovered checkpoints remain available through another crash before autosave; restarting IDs and explicit recovery from another folder preserve unopened snapshots. Successful Save, Close or Revert clears the document's checkpoints, including manual recovery while autosave is disabled; failed republishing keeps the original. Concurrent older versions still use unlocked root entries; mixed-version isolation remains open. File › Revert and Save a Copy…; `file.recovery.*`, `file.revert`, `file.saveACopy`.

 - Graphics backend chosen before the window exists (DirectX 12 on Windows, Vulkan on Linux, Metal on macOS, OpenGL as the fallback; `WGPU_BACKEND` overrides) with a start-up fallback: a backend whose start never showed a frame is skipped at the next start and the status bar says so (`gpu.json`). Found on an AMD hybrid-graphics laptop whose Vulkan driver faulted at the first present.
 - Graphics adapter chosen by the app: the GPU that drives the primary display (Windows `EnumDisplayDevices`, Linux sysfs), then the power preference (`WGPU_POWER_PREF`, `WGPU_ADAPTER_NAME` override). An adapter that fails or hangs while the window starts is left out and the app starts again on the next one, then on the next backend, with software renderers last; wgpu's indirect-call check is off (it lost the Metal device on an Intel Mac, #334); why the app stopped is logged, also when the window never opened (#273). Ported from VectorCraft.
 - Edit › Paste Into (copied objects become a frame's content, clipped by it; rendered, PDF and IDML both ways — verified in InDesign 2026); Polygon Settings (sides, star inset; double-click the Polygon tool).
