Make video projects, with a moving channel split as the first video effect

Browse Source 
A project can now be a clip: Setup has a Video switch with a length, a
frame rate and presets that set the canvas too (Instagram story, reel and
feed video, TikTok / YouTube Short, Square loop, Full HD clip). The preview
renders the whole clip, shrunk to a memory budget, and loops it with
play/pause and a scale; Save As... renders it again at full size and pipes
the frames into ffmpeg as .mp4, .mov, .mkv, .webm or .gif, with a progress
window that can cancel. --duration, --fps and --video-preset do the same
from the command line.

Effects learn about time through FrameTime and Effect::renderFrame, which
falls back to render, so nothing that holds still changes. Channel split
now sways, shakes and rolls a tracking bar down the picture in a video; its
motion params are marked forVideo() and hidden in a still project, and a
still renders byte for byte as before. renderFrames starts every frame
from the same seed and renders the still stages ahead of the first moving
one only once. The version moves to 0.6.0.

## [0.6.0] - 2026-09-26
### Added
- Video projects: switch Video on under Setup and give the clip a length and a
frame rate, or pick a preset that sets the canvas too: Instagram story,
Instagram reel, Instagram feed video, TikTok / YouTube Short, Square loop and
Full HD clip. The preview renders the clip and loops it, with play/pause and
a scale to look at any one frame.
- Save As… writes a video project as `.mp4`, `.mov`, `.mkv`, `.webm` or `.gif`
through `ffmpeg`, with a progress window that can cancel it.
- Channel split moves in a video: its channels sway, shake from frame to frame
and a tracking bar rolls down the picture, like an old tape on a tube. The
new Wobble, Jitter and Tracking bar settings show only in a video, and a
still renders exactly as before.
- `--duration`, `--fps` and `--video-preset` render a video from the command
line.
- A Vertical Full HD canvas format, 1080 × 1920.
