fix(cli): expose init command at root

[codexwizardd]

Summary

• extract the existing ship init command into a factory so it can be mounted in more than one place
• keep sh1pt ship init behavior unchanged
• expose documented root-level sh1pt init for scaffolding sh1pt.config.ts

Verification

• npm run typecheck (packages/cli)
• npm run build (packages/cli)

Runtime help check note: node dist/index.js --help and node dist/index.js init --help still fail before command parsing with the existing workspace resolution error: Cannot find module '/workspace/sh1pt/packages/core/src/target.js' imported from /workspace/sh1pt/packages/core/src/index.ts.

Closes #241

Related to the accepted Ugig sh1pt CLI command gig.
