Second part of the Spanish update, after #945.

• navigate.yaml follows the English file; the old Spanish one used the previous scheme.
• NavigationParts in definitions.yaml translated (en numerador, fuera de denominador, en límite inferior...), plus the inverse-function intent name.
• tests/Languages/es/navigate.rs: the English tests plus Spanish-only cases (one-sided limits, lím, babel's arc sen).

Navigating \frac{x+1}{2} (NavVerbosity medium):

command	English	Spanish
ZoomIn	in numerator; x plus 1	en numerador; x más 1
MoveNext	in denominator; 2	en denominador; 2
ZoomOut	out of denominator; the fraction with numerator; x plus 1; and denominator 2	fuera de denominador; la fracción con numerador; x más 1; y denominador 2
ToggleZoomLockDown	simple mode; x plus 1	modo simple; x más 1

cargo test passes. Listened with NVDA 2026.3 and the MathCAT 0.7.8-alpha.1 add-on in Acrobat: limits, fractions, roots, mixed numbers and matrices navigate without errors.

That was quick! Thanks.

@NSoiffer To be honest, it’s a bit of a cheat :D ...I’ve been working on this for over a year; ever since I started developing a LaTeX package, I’ve been listening to and navigating through a lot of tagged PDFs. However, I had no way—and it was a real struggle—to compile MathCAT on Windows, so I only had the patches in theory. Once you made the MathCAT add-on available, I was finally able to run tests and hear how things actually sound, which allowed me to make progress... Have you considered providing nightly builds of the add-on? It would make things much simpler for those of us who want to contribute (compiling from source is a real headache).
