feat(pgpm): add -w alias for --workspace flag and migrate to genomic

Summary

This PR enables users to run pgpm init -w or pgpm init --workspace to create a new workspace when not inside an existing one. The changes include:

• Renamed --createWorkspace flag to --workspace with -w alias in pgpm init command
• Migrated from create-gen-app to genomic package (which uses [email protected] with the new alias feature)
• Updated inquirerer to v4.1.0 across all packages to resolve type conflicts

The alias feature was implemented in a separate PR to the dev-utils repo (constructive-io/dev-utils#43) and published as [email protected].

Review & Testing Checklist for Human

• Test the alias functionality: Run pgpm init -w and pgpm init --workspace outside a workspace to verify both trigger workspace creation
• Verify template scaffolding still works: The migration from create-gen-app to genomic should be API-compatible, but test that pgpm init inside a workspace still scaffolds modules correctly
• Check cache command: Run pgpm cache clean to verify the CacheManager import from genomic works correctly

Recommended Test Plan

1. Navigate to a directory outside any PGPM workspace
2. Run pgpm init -w - should prompt to create a workspace
3. Run pgpm init --workspace - should behave identically
4. Inside the new workspace, run pgpm init to create a module and verify scaffolding works

Notes

• The create-gen-app package was deprecated in favor of genomic, which already uses [email protected]
• The large pnpm-lock.yaml diff is mostly formatting changes plus the dependency updates
