- Add slcompose.sh: Central orchestrator for managing all Docker services
  * Boot all services at startup with automated Infisical secret injection
  * Commands: up, down, restart, logs, logs-tail, env, env-all
  * Colored environment variable output (blue names, green values)

- Add slcompose.service: Systemd service file for auto-boot on startup
  * Type=oneshot with RemainAfterExit=yes
  * Waits for Docker service before starting
  * Runs on multi-user.target

- Add orchestration.md: Comprehensive documentation
  * Architecture and installation guide
  * Usage examples for all commands
  * Secret injection flow and troubleshooting
  * Performance and security notes

- Update README.md and AI_CONTEXT.md
  * Document service orchestration architecture
  * Explain slcompose functionality and commands
  * Reference new orchestration documentation
