David Snelling ddcc0c723d refactor(8.0): remove the 4 deprecated query-operator aliases (clean break)
8.0 keeps the canonical operators (eq/ne/gt/gte/lt/lte) and their clean
long-form aliases (equals/notEquals/greaterThan/greaterThanOrEqual/lessThan/
lessThanOrEqual), and drops the four redundant deprecated spellings:
  is → eq,  isNot → ne,  greaterEqual → gte,  lessEqual → lte

Removed from every evaluator (metadataIndex criteria + range switches,
metadataFilter, the db whereMatcher egress path) and from the
BrainyFieldOperators type, the unsupported-operator error message, the docs
(QUERY_OPERATORS / api README / VFS projection + semantic guides), and the
whereMatcher alias tests. Also migrated Brainy's own internal use — the VFS
TemporalProjection queried with greaterEqual/lessEqual, which would have
silently broken — to gte/lte.

Full gate green: build, unit 1512, integration 607.

Brainy Documentation

The multi-dimensional AI database with Triple Intelligence — vector search, graph traversal, and metadata filtering in one unified API.

Quick Start

import { Brainy, NounType, VerbType } from '@soulcraft/brainy'

const brain = new Brainy()
await brain.init()

// Add entities — data is embedded for semantic search, metadata is indexed for filtering
const id = await brain.add({
  data: 'Revolutionary AI Breakthrough',
  type: NounType.Document,
  metadata: { category: 'technology', rating: 4.8 }
})

// Search with Triple Intelligence
const results = await brain.find({
  query: 'artificial intelligence',              // Semantic search (on data)
  where: { rating: { greaterThan: 4.0 } },       // Metadata filter
  connected: { from: authorId, depth: 2 }         // Graph traversal
})
