v1.0.4

Full Changelog: v1.0.3...v1.0.4

Added

• Model-download integrity. Each downloaded model is verified against a pinned SHA-256 before it's installed, so a corrupted or substituted file is rejected and re-fetched instead of being loaded into the runtime.
• Per-monitor DPI awareness (Per-Monitor V2). Stickers stay sharp and hit-test correctly when dragged across monitors with different display scaling, instead of being bitmap-stretched.
• Stickers remember their model across a restore. A restored sticker comes back with the model it was matted with when that cutout is still cached (instant); otherwise it falls back to the default model, so --resume never kicks off a slow re-matte at login.

Fixed

• Matte no longer races session teardown. All matting is serialized through one gate, so switching models, trimming GPU memory, or evicting an idle session can no longer dispose an ONNX session mid-inference (which could crash the app). Model load/download also no longer holds the session lock, so quitting during a first-run download won't hang.
• Single-instance pipe is isolated per session, with a current-user-only ACL and a backoff on the listener — a second login session on the same machine can no longer collide with it or spin the CPU.
• Clipboard captures are pruned instead of piling up forever under ~/.sticker_cache/clipboard.
• Session writes are debounced off the UI thread, so rapid resize/opacity changes no longer rewrite session.json on every notch; the session is flushed synchronously on exit.
• Crash resilience. A stray UI-thread exception is now surfaced and survived instead of taking down the tray and every open sticker; a fatal background error still flushes the session first so nothing is lost.
• Rotate menu labels no longer advertise R / Shift+R next to the 90° items (those keys rotate 15°, the menu items 90°).
• "Close all stickers" can't get stuck suppressing session saves if a window throws while closing.
