feat: define shared swarm config schema (Issue #4)

- Add config.yaml.example as multi-agent swarm schema
- 7 bot users across 3 platforms: hermes (4), pi (1), agent-zero (1), @all-bots
- All owner_email values confirmed:
  - tanko, mumuni, abiba, kagentz -> jerome@sysloggh.com
  - koonimo -> jeremytabiri@gmail.com
  - koby -> theo@sysloggh.com
- DRY: deploy.sh AGENTS array should derive from config.yaml in future
- config.yaml is gitignored (secrets-safe); created locally with full data
