feat(social): person enrollment system — SQLite gallery + voice trigger (Issue #87)
- saltybot_social_msgs: 6 msg + 5 srv definitions for social interaction
- saltybot_social_enrollment: enrollment_node + enrollment_cli
- PersonDB: thread-safe SQLite-backed gallery (embeddings, voice samples)
- Voice-triggered enrollment via "remember me my name is X" phrase
- CLI: enroll/list/delete/rename via ros2 run
- Services: /social/enroll, /social/persons/list|delete|update
- Gallery sync from /social/faces/embeddings topic
