- Fix bug in extractURL where multi-token option blocks like
[arch=amd64 signed-by=/path/key.gpg] were not properly skipped,
causing the option value to be returned instead of the URL
- Add comprehensive unit tests for parseList, parseSearch, parseInfo
edge cases (empty input, missing fields, special characters)
- Add unit tests for normalizeName and parseArch covering all
supported Debian architectures and edge cases
- Add unit tests for formatTargets, buildArgs (all option combos),
and extractURL (basic, options, signed-by)
- Coverage: apt package 7.5% -> 17.1%
