Template DX: example config completeness + fork checklist

[crazycloudcc]

Goal

First-run experience after "Use this template" is boringly reliable.

Scope

• ccblog.config.example.ts comments cover every public field
• README Fork & deploy checklist matches current scripts
• Sensible features.* defaults for a personal fork
• Troubleshooting: blank search, wrong OG URL, playground toolchain offline

Acceptance

• Example config alone is enough to rebrand without reading source
