/ship is back in the slash-command index

The ship skill's description contained a colon followed by a space inside an unquoted YAML value, which is a parse error; Claude Code drops a skill whose frontmatter does not parse and says nothing, so a fresh session found nine skills and No commands match "/engineering-loop:ship". Every skill description is now a double-quoted scalar, and tests/test-skills-frontmatter.sh parses each one with a strict reader in CI.
