/**
 * 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
