Tools for recording clean footage of the game, so promo videos no longer need a private copy of the code.

**What changed**

- `--no-markers` hides every test overlay and placeholder marker: side rings, name tags, charge glow, ground-pound and landing rings, blast shapes, the melta cone flash, spawn-room shield planes, Seize Ground point columns and debug text. The HUD stays (`--no-hud` hides it). Gameplay is unchanged, and without the flag nothing looks different.
- `movie.cmd --movie-size WxH --write-movie file.avi` records at a chosen frame size (for example 1080x1920 or 1080x1080) without touching the project itself. It refuses to write inside the repository or the game install.
- `--spectate inspect` slowly orbits the player's own weapon.

**What it looks like**

The two screenshots are the same spot on Manufactorum with and without the marker overlay (the yellow ring is the side marker, a placeholder).

**What is not covered**

The rings, blasts and melta flash under `--no-markers` are switched off in code but were not captured on screen.
