feat: v0.57.0 - rename CLI to brainy and Neural Import to Cortex

BREAKING CHANGES:
- CLI command renamed from 'cortex' to 'brainy'
- Neural Import renamed to Cortex augmentation
- Class CortexSenseAugmentation (was NeuralImportSenseAugmentation)

Benefits:
- npx @soulcraft/brainy now works automatically
- Better conceptual clarity: Cortex = AI intelligence layer
- Cleaner architecture: CLI = brainy, AI = Cortex, DB = BrainyData
