I often see “rail systems” or “rods” sold for DSLR and mirrorless video setups: two rods running under or alongside the camera. What are they for, and how are they different from a macro focusing rail?

It sounds like you're talking about the kind of rail system that's used for mounting video equipment. There's some detailed information here and a video here but in a nutshell a rail system is the foundation upon which all kinds of video equipment is mounted. That includes the camera, of course, but also sound equipment, follow focus adjuster, matte box, additional displays and interfaces, lights, batteries, shoulder mount, tripod mount, perhaps even a teleprompter. The rods come in standard sizes (15mm or 19mm) and are arranged in standard configurations with respect to the center of the lens, so that equipment from various manufacturers works together.

In this context, rods/rails are part of a video support rig, not a macro focusing rail.
A video rod system is a modular mounting framework built around the camera. The rods let you attach and position accessories such as:
- follow focus units
- matte boxes
- microphones or audio gear
- external monitors/interfaces
- lights
- battery mounts
- shoulder or tripod supports
- even teleprompter-related gear
A key benefit is standardization: video rods commonly use standard diameters such as 15mm or 19mm, with accessories designed to align correctly relative to the lens center. That makes it easier to mix gear from different manufacturers.
So, yes: a macro focusing rail is a different thing. A focusing rail is used to move the camera precisely for close-up work and focus stacking, while video rods are mainly for building out and supporting a camera rig and its accessories.
