and the fix that leaked in- Why this PR also fixes punctuated milestone titles:

The interactive list compares raw milestone titles, but the CLI was handing it a normalized value (Release-1 → release 1). So -m "Release-1" matched nothing there — same root cause as the ID bug, just a different input tripping it.
Both are the same one line in cli.ts. Making ID queries work in the interactive list requires handing it a real title, which fixes punctuated titles at the same time. Splitting them would have meant shipping ID lookups that only work for milestones whose titles happen to contain no punctuation.
