v2.3.2: fix truncated download cache, update Discord link

Fix pre-release downloads failing with "unexpected EOF" by validating
cached PWR file sizes against manifest expected sizes. Previously only
checked > 1MB which accepted truncated files. Also update Discord
invite link to new server across all files.
