Adds `flair rem` command group with three subcommands:
- `rem light` (NREM): MemoryMaintenance + ConsolidateMemories, shows expired/archived/promotion/archive candidates, supports --dry-run
- `rem rapid` (REM): ReflectMemories, outputs structured LLM reflection prompt, supports --focus and --since
- `rem restorative` (deep audit): all three in sequence with olderThan=7d for consolidation, full report
All subcommands accept --port and --agent (falls back to FLAIR_AGENT_ID env).
