Sistema de extracción de funciones desde repos externos. Agrega campos source_repo, source_license y source_file en functions y types (migración 006). Incluye manifest sources/sources.yaml, regla sources.md, parser con campos de atribución, y template actualizado con los nuevos campos.

## Ejemplo
|
|
|
|
```go
|
|
evens := FilterSlice([]int{1, 2, 3, 4}, func(n int) bool { return n%2 == 0 })
|
|
// evens = [2, 4]
|
|
```

|
## Notas
|
|
|
|
Funcion pura generica. No muta el slice original — crea uno nuevo.
