Refactor CLI into modular Commander commands

[cre8]

Summary

Refactor the EUDIPLO CLI into modular Commander.js command modules and service layers to make future command extensions easier.

• Split command registration and actions into focused modules.
• Move configuration, deployment, diagnostics, and project-directory logic into services.
• Preserve Compose, demo, instance, doctor, status, version, and config workflows.
• Add discoverable tenant validation commands: eudiplo config tenant validate <tenant-id> validates one local tenant; without an ID it validates all local tenants. Existing path-based config validate tenant(s) <path> commands remain supported.
• Update CLI documentation, asset handling, and tests.

Verification

• pnpm --filter @eudiplo/cli test (67 tests)
• pnpm --filter @eudiplo/cli build
• pnpm --filter @eudiplo/cli lint
• pnpm knip
• Repository pre-push format and lint checks passed.
