v0.3.1 — czap ship fails closed on unknown flags

[0.3.1] - 2026-06-19

Fixed

• @czap/cli — czap ship now fails closed on unrecognized flags. The arg
  parser silently ignored any unknown -/-- flag (including --help), so
  czap ship --help — or any typo'd flag — fell through to "no --filter →
  publish EVERY workspace package." --help/-h now print usage and exit
  without shipping, and any unrecognized flag is refused (exit 1) before a single
  package is packed or published. Long-latent (present since ≥0.2.3), auth-gated;
  hardened here so a flag typo can never trigger a publish.
