Preset state lost on service restart #5

When the pedal service restarts, it forgets the active preset and jumps to bank 1 program 1 (empty default). The UI shows an empty chain.

Root cause: PresetManager saves current_bank/current_program on change but doesn't reload them on init.

Fix:

  • Load saved state in PresetManager.init() or select() default path
  • Activate the last preset during startup so the UI shows correct blocks
  • State endpoint should handle 'no valid preset' gracefully

Labels: bug, priority/high

Fixed in commit 47bb535. Added self.restore_state() call at the end of PresetManager.init() so last active preset is tracked after boot.
