Fetch TinyTeX URLs dynamically from GitHub releases API - #7
Merged
Conversation
Gli URL di TinyTeX erano scritti a mano (TinyTeX-1.zip sui tag "daily" e "latest", più il redirect di yihui.org). Le release di tinytex-releases ora allegano archivi con la versione nel nome (TinyTeX-1-v2025.08.zip), quindi tutte e tre le fonti rispondevano 404 e l'installazione falliva: senza distribuzione, anche la pagina Pacchetti restava inutilizzabile. Ora gli indirizzi si ricavano dall'API delle release: fra gli allegati con l'estensione della piattaforma si preferisce TinyTeX-1, poi le altre varianti, scorrendo le release dalla più recente. Gli URL fissi restano solo come riserva se l'API non è raggiungibile. In più: il nome dell'archivio temporaneo segue la piattaforma e non l'URL (è quello che decide come estrarlo), gli archivi sospetti sotto 1 MB sono scartati come fonti non valide, e il messaggio d'errore finale spiega come usare TEXFORGE_TINYTEX_URL.

Summary
Refactored TinyTeX download mechanism to dynamically fetch available releases from the GitHub API instead of relying on hardcoded URLs. This makes the installation more resilient to naming scheme changes and new release formats.
