tinkle-community 773857351f feat(grid): auto-adjust grid direction based on box breakouts
Add GridDirection type with 5 states:
- neutral (50% buy + 50% sell)
- long/short (100% one direction)
- long_bias/short_bias (70%/30% configurable)

Direction adjustment logic:
- Short box breakout → bias direction (long_bias/short_bias)
- Mid box breakout → full direction (long/short)
- Long box breakout → emergency handling (unchanged)
- Recovery: long → long_bias → neutral ← short_bias ← short

Config options:
- EnableDirectionAdjust (default: false)
- DirectionBiasRatio (default: 0.7)

Includes unit tests for all direction-related functions.
