add --no-dl/-N option to skip downloads and set NODOWNLOAD=yes

Adds --no-dl/-N flag for use with --hintfile or --new. Skips wget,
inserts NODOWNLOAD=yes after MD5SUM_x86_64 in the hint file. Also
fixes README (correct paths, old command name, missing --delete/--clean
sections) and updates CLAUDE.md and bash completion accordingly.
