feat: rename inquirerer to commodore and create @commodore/utils package

Summary

This PR performs a major refactoring of the CLI-related packages in dev-utils:

1. Renamed inquirerer → commodore (v3.0.0): The main CLI prompt library with the Inquirerer class renamed to Commodore
2. Renamed create-gen-app → @commodore/scaffolds (v1.0.0): Template scaffolding utility
3. Created @commodore/utils (v1.0.0): New package with CLI lifecycle utilities extracted from constructive repo:
   • extractFirst() - command routing utility
   • cliExitWithError() - error handling with optional cleanup hooks
   • checkForUpdates() - npm version checking with configurable registry
   • getSelfPackageJson() - package.json resolution helpers
4. Added subpath export for commodore/test-utils

All internal references and dependencies have been updated. Build passes successfully.

Review & Testing Checklist for Human

• Verify @commodore npm scope access - Ensure the @commodore org is properly configured on npm before publishing
• Test downstream consumers - The constructive repo (pgpm CLI, cnc CLI) still needs to be updated to use these new packages (Phase 2 not included in this PR)
• Review hardcoded version in create-gen-app-test - packages/create-gen-app-test/src/cli.ts has PACKAGE_VERSION = '1.0.0' hardcoded instead of reading from package.json
• Verify @commodore/utils utilities - The new utilities are untested (no test files created). Consider adding tests before publishing.
• Test subpath export - Verify import { ... } from 'commodore/test-utils' works correctly after build

Recommended Test Plan:

1. Run pnpm install && pnpm build to verify everything compiles
2. Run pnpm test to ensure existing tests pass
3. Manually test importing from the new package names in a test project
4. Do NOT publish until the constructive repo is updated to consume these packages

Notes

BREAKING CHANGES:

• inquirerer → commodore (class Inquirerer → Commodore)
• create-gen-app → @commodore/scaffolds
• All consumers must update their imports

Not included in this PR:

• Updates to constructive repo (pgpm/cnc CLIs) - planned as Phase 2
