- single daemon process manages all services in memory
- CLI communicates via Unix socket, does not read config
- config hot-reload: daemon polls config.toml, reacts immediately
- rename-safe: removing a service from config kills it, adding starts if enabled
- logs remain file-based for direct reading by rss logs
- removed per-service PID files, supervisor module simplified
- rss daemon kills and cleans services not in config (rename-safe)
- rss list also prunes orphaned state
- rss start checks for already running before spawning
- State: add supervise_dir/service_dir/list_pid_names helpers
- start/stop/restart/status/logs/enable/disable/list/daemon
- PID-file based state, no daemon, no root
- config.toml with placeholders, restart policies, env vars
- log tailing with -n/-f and stderr colorization
- supervisor per service with SIGTERM handling
