docs: the Polish technicians' and beginners' guides rewritten in natural Polish; vectors in every guide

Browse source 
- dla-technikow.md and dla-poczatkujacych.md written anew from the English, in plain Polish
  (no calques, the same words for the same things in every guide, addressing every reader alike)
- the technicians' guides (en, pl): "Variants that hold values" moved to the enums section;
  the examples list has wordcount and simd
- src/embedded.fch packs the runtime with its updated comment

### Variants that hold values
A variant can carry values. Make one with `Shape.Circle(2.0)`, take them out with `match`, which names them:
```c
enum Shape {
Circle(float)
Rect(float, float)
Point
}
fn Shape.area() -> float {
return match self {
Circle(r) -> 3.14 * r * r
Rect(w, h) -> w * h
Point -> 0.0
}
}
```
`_` ignores a value. `match` must handle every variant (or end with `else`). Printing shows `Rect(2, 3.5)`. Such an enum is
copied and freed like a struct; it can't be compared with `==` (match on it). Variants of these enums can't have numbers.
