Summary

When parsec ship fails to create a PR, it still prints "Shipped!" and returns exit code 0. Users discover the missing PR too late.

Proposed Solution

• On PR creation failure: print "Shipped (partial)" or a clear warning
• Return non-zero exit code
• Include pr_created: false in --json output

Context

All 4 ships displayed "Shipped!" → actually no PRs were created → discovered late and had to create PRs manually with gh
