Follow-up fixes to PR #1006:
- Silence deprecation warnings when --json flag is set (agent ergonomics)
- Remove unused outputStatusJSON() function
- Remove unused encoding/json import from daemon_status.go
Agents parsing JSON output dont need deprecation warnings cluttering stderr.
The subcommand syntax (bd daemon start) remains the documented path forward.
See bd-ntl3b for deduplication work, bd-kpa7c for type consolidation.
