feat(cutter): add crash-safe project recovery and export profiles

Persist source-bound cutter projects atomically and expose recovery, discard, save, and open actions through the secured IPC bridge. Add explicit quality, balanced, fast, and archive export pipelines with rotation, audio-track selection, hardware encoder probing, and software fallback. Align main, preload, renderer, UI styles, and focused coverage; remove the reported main-process lint errors without changing unrelated work.
