# ============================================================================
# DAEMON ROUTING - ENABLED (Phase 3.7: CLI Daemon Integration)
# ============================================================================
# Redesigned daemon with pre-loaded Nushell environment (no CLI callback).
# Routes eligible commands to HTTP daemon for <100ms execution.
# Gracefully falls back to full load if daemon unavailable.
#
# ARCHITECTURE:
#   1. Check daemon health (curl with 5ms timeout)
#   2. Route eligible commands to daemon via HTTP POST
#   3. Fall back to full load if daemon unavailable
#   4. Zero breaking changes (graceful degradation)
#
# PERFORMANCE:
#   - With daemon: <100ms for ALL commands
#   - Without daemon: ~430ms (normal behavior)
#   - Daemon fallback: Automatic, user sees no difference
