chore: recovery checkpoint - v3.0 API successfully recovered

CRITICAL CHECKPOINT - DO NOT PUSH TO GITHUB

Recovery Status:
- Successfully recovered brainy.ts from compiled JavaScript
- All core v3.0 API methods functional (add, get, update, delete, relate, find, etc.)
- Neural subsystem intact (562KB embedded patterns, NLP working)
- Augmentation pipeline operational (20+ augmentations)
- HNSW clustering system complete
- Triple Intelligence compiled (needs constructor fix)
- Test suite validates functionality

Changes preserved:
- 898 files with changes from last 3 days
- 144,475 insertions
- All augmentation improvements
- All test coverage enhancements
- Complete v3.0 feature set

This is a LOCAL checkpoint only - contains recovered work after corruption incident.

+/**
+ * Base Synapse Augmentation
+ *
+ * Synapses are special augmentations that provide bidirectional data sync
+ * with external platforms (Notion, Salesforce, Slack, etc.)
+ *
+ * Like biological synapses that transmit signals between neurons, these
+ * connect Brainy to external data sources, enabling seamless information flow.
+ *
+ * They are managed through the Brain Cloud augmentation registry alongside
+ * other augmentations, enabling unified discovery, installation, and updates.
+ *
+ * Example synapses:
+ * - NotionSynapse: Sync pages, databases, and blocks
+ * - SalesforceSynapse: Sync contacts, leads, opportunities
+ * - SlackSynapse: Sync messages, channels, users
+ * - GoogleDriveSynapse: Sync documents, sheets, presentations
