Adds liuverse-movie: short films set on the campus, drawn by the game's own
renderer and encoded with ffmpeg.

liuverse-render grows an offscreen target: the present pass lands in a
texture instead of the swapchain, and the frame is read back as RGBA.
liuverse-movie owns the Movie trait, the studio (campus, renderer, frame
clock, encoder), an Actor that walks with the game's gait solver, and the
catalog of films. Two films ship: a sunrise flyover and two students on a
campus path.
liuverse-assets holds the campus's palette, tuning and asset registry, so
the game and the films share one campus. The camera poses and the cinematic
overlay move with them.

(slop) render films offscreen and encode them with ffmpeg fbcd9100b4

A film is a timeline: it says how long it is and draws one frame at a
time. The studio owns the campus, the renderer, the frame clock and the
encoder, so a new film is one type and one catalog line.

The renderer grows a second target: the same present pass lands in a
texture instead of the swapchain, and the frame is read back as RGBA.
The campus's palette, tuning and asset registry move to `liuverse-assets`,
so the game and the films cannot drift apart, and the camera poses and
the cinematic overlay are shared with the client.
