feat: local-first template resolution (cna.config.json + --set flag)

- Remove yargs dependency (ESM-only, breaks CJS bundle); replace with
  prompts.override(options) using already-parsed Commander values
- Add --set key=value CLI flag for overriding custom template options
- Add loadTemplateCnaConfig() to core: reads cna.config.json from the
  template root directory (not inside template/ subdir)
- Add getTemplateBaseDirPath() to core: resolves base dir without the
  template/ subdir detection that getTemplateDirPath() applies
- processNonInteractiveOptions: load cna.config.json and apply initials
  (priority: --set > cna.config.json > registry templates.json)
- processInteractiveOptions: merge cna.config.json customOptions with
  registry, apply --set as prompt initials
