v0.5.0

• Split and splice clips like Monologue: the timeline now holds multiple clips — S or double-click splits, drag any clip's handles to trim it, double-click a gap or split to join, and X/Delete removes or restores a clip
• [ and ] jump between clip edges, Ctrl+Z / Ctrl+Shift+Z undo and redo, and Z zooms to the clip
• Playback skips the gaps, and export joins the kept clips into one video, with audio
• AV1 videos no longer preview black on machines whose GPU can't decode AV1 in hardware — Omacut now falls back to software decoding
