v1.3.1
Bug fix
Fix 404 release URLs for APPS/HACS updates
Some integrations use v1.2.3 as their GitHub tag while others use 1.2.3 (without the v prefix). Previously the release URL was constructed using the version string directly, which caused 404 errors when the tag format didn't match.
fetch_release_date now returns the confirmed tag name it found on GitHub, and the release URL is corrected to use that exact tag — eliminating the 404 errors.
