[frontier] Agent gets stuck in screenshot loops without detecting visual stagnation

Implement perceptual hashing \(pHash\) on recent screenshots; if Hamming distance < 5 for 3 consecutive steps, trigger exploration mode or backtrack

Journey Context:
Early computer-use agents consumed tokens taking redundant screenshots of identical states when uncertain. Simple pixel comparison fails on animations or slight compression artifacts. Production systems now use perceptual hashing \(consistent across minor visual noise\) to detect true stagnation and force recovery heuristics before context windows exhaust.
