Thad says this is a compiler bug, rather than fight it, let's use a new
code path through the compiler.

It's only syntactic sugar over the CommandScheduler's schedule method and creates a footgun because it’s too obvious to try to use in incorrect places.

This has the same effect but makes it so any user code returning CommandPtr can't discard a returned command.

This enables frc-docs to use RLIs for things that are currently in-line
code blocks, and ensures they compile, which is important with the 2027
breaking changes coming. They are kept separate from the examples to
ensure they don't polute the VSCode examples finder.
Adds the Encoder snippets used in the frc-docs Encoder article as the
first instance of this.
* Move units into API docs instead because suffixes make user code verbose and hard to read
* Rename trackWidth to trackwidth
* Make ultrasonic classes use meters instead of a mix of m, cm, mm, ft,
and inches
