feat(spawn): citizen classes, setup script, gitignore, README rewrite
- Spawn: builder/birthright templates replace agent.template, passport command,
class-aware create/update (FPLAN-0009)
- setup.sh: one-command install (venv, pip, hooks, registry generation)
- .gitignore: comprehensive coverage for all runtime state (.trinity/,
.ai_mail.local/, DASHBOARD.local.json, *_json/, logs/, etc.)
- README.md: rewritten for accuracy — removed fictional plugin docs,
fixed architecture pattern, corrected module statuses
- Hooks moved to global ~/.claude/settings.json (absolute paths)
