chore: add justfile with common commands

Recipes wrap the documented bun/turbo/cargo/docker commands; 'just test ' passes through to bun test, 'just dev' ensures .env.local exists. just is added to the nix devshell so it is available after nix develop.

feat: freeze frame at playhead

Enable the timeline toolbar freeze-frame button: capture the composited canvas as PNG, add it as an image media asset, split the video element at the playhead, shift the right part by the freeze duration, and insert a 3-second image element in the gap. Adds RendererManager.captureFrame(), reused by createSnapshot(). Also adds the Nix devshell (flake.nix/flake.lock: bun + nodejs) and AGENTS.md repository guidelines.
