Add comprehensive test suite for Spanish keyword translation

[Copilot]

The rustico procedural macro lacked test coverage for its Spanish-to-English keyword translation functionality.

Changes

Added 44 integration tests across 7 test files covering:

• Core syntax - functions (función), variables (sea, mutable), control flow (si/sino, machea, para, mientras, bucle)
• Type system - signed/unsigned integers (e32/n32), booleans (bul, verdad/falso), strings (Cadena)
• Option/Result - Opcion<T>/Resultado<T, E> with Alguno/Ninguno, Bien/Error, and methods (pelar, confia)
• Structs/Enums - estructura, enumerado, implementa, visibility (púb)
• Traits - rasgo, trait implementations, Self references (Yo/Mismo)
• Stdlib - Diccionario (HashMap), Conjunto (HashSet), Caja (Box)
• Keyword alternatives - accented variants (función/funcion) and synonyms (deja/sea, retorna/devuelve)

Updated CI workflow to run tests on every commit:

• Added test step to .github/workflows/ci.yaml to execute cargo test --all
• Fixed code formatting with cargo fmt --all to pass existing CI checks

Example

#[test]
fn test_basic_function() {
    rustico::rustico! {
        función prueba() -> e32 {
            sea x = 5;
            si x > 3 {
                retorna x * 2;
            } sino {
                retorna 0;
            }
        }
    }
    
    assert_eq!(prueba(), 10);
}

Tests verify the macro correctly translates Spanish keywords to their English equivalents and the resulting code compiles and executes as expected. CI now automatically runs all tests on every commit to ensure code quality.

@copilot Please update the CI to run this tests every commit also run cargo fmt --all -- --check so it passes the current CI
