Power management profiles for edge deployment

[SuperInstance]

Problem

Jetson Orin Nano has 35W budget. No power management profiles defined.

Proposed Solution

• Full power profile: all features, GPU active
• Economy profile: reduced GPU, background tasks paused
• Emergency profile: navigation-only, minimum compute
• Auto-switch based on battery level
• Integration with Cocapn priority queue

Acceptance Criteria

• 3 power profiles defined and tested
• Auto-switch triggers at configurable thresholds
• Navigation never interrupted by profile switch
