Fix updater SHA512 mismatch by patching latest.yml filenames and adding integrity retry
Build and Release / build (push) Has been cancelled
Details

Browse Source 
- Patch latest.yml during release to use actual filenames (spaces) instead of electron-builder's dashed names
- Add download size validation before SHA512 check to catch incomplete downloads
- Retry download on integrity mismatch (up to 3 passes) with API refresh
- Re-resolve digest from latest.yml on each retry pass
