feat(cli): add remote template fetching via giget (#162)

* feat(cli): add remote template fetching via giget

* fix: update remote.ts to use templates/ instead of examples/

* fix(cli): validate template ID against manifest before downloading

Fails fast with available template list instead of downloading
an empty directory for nonexistent templates.

* refactor(cli): simplify to single --template flag with dynamic validation

- Remove --example flag (--template handles bundled + remote)
- Remove static ALL_TEMPLATE_IDS list (validates against GitHub manifest)
- No CLI release needed to add new templates — just add to templates/ and templates.json
- scaffoldProject auto-detects bundled vs remote

* chore: update lockfiles for giget dependency

* fix(cli): remove undefined isAudioOnly reference
