feat: remove legacy ImportManager, standardize getStats() API

- Removed ImportManager class and exports (use brain.import() instead)
- Fixed all documentation: getStatistics() → getStats()
- Updated 41 files across codebase for consistency
- Removed ImportManager section from API docs
- Added v3.30.0 migration guide to CHANGELOG

-## Import API
-
-### `createImportManager(brain: Brainy): ImportManager`
-Creates an import manager for intelligent data import.
-
-**Example:**
-```typescript
-import { Brainy, createImportManager } from '@soulcraft/brainy'
-
-const brain = new Brainy({ preset: 'memory' })
-await brain.init()
-
-const importer = createImportManager(brain)
-await importer.init()
-```
-
----
-
-### `async ImportManager.import(source, options?): Promise<ImportResult>`
-Import data from various sources with AI-powered entity detection.
-
-**Parameters:**
-- `source` - String, Buffer, array, or object to import
-- `options.source` - 'data' | 'file' | 'url' | 'auto' (default: 'auto')
-- `options.format` - 'json' | 'csv' | 'text' | 'yaml' | 'auto' (default: 'auto')
-- `options.batchSize` - Batch size for processing (default: 50)
-- `options.autoDetect` - Auto-detect entity types (default: true)
-- `options.typeHint` - Suggested entity type
-- `options.extractRelationships` - Extract relationships (default: true)
-- `options.csvDelimiter` - CSV delimiter character
-- `options.csvHeaders` - CSV has headers (default: true)
-- `options.parallel` - Process in parallel (default: true)
-- `options.maxConcurrency` - Max concurrent operations
-
-**Returns:**
-```typescript
-{
-  success: boolean
-  nouns: string[]        // IDs of imported entities
-  verbs: string[]        // IDs of created relationships
-  errors: string[]
-  stats: {
-    total: number
-    imported: number
-    failed: number
-    relationships: number
-  }
-}
-```
-
-**Examples:**
-
-```typescript
-// Import from CSV file
-const result = await importer.importFile('./data.csv', {
-  format: 'csv',
-  extractRelationships: true
-})
-
-// Import from URL
-const result = await importer.importUrl('https://api.example.com/data.json')
-
-// Import array of objects
-const data = [
-  { name: 'Alice', role: 'Developer' },
-  { name: 'Bob', role: 'Designer' }
-]
-const result = await importer.import(data, {
-  typeHint: NounType.Person,
-  extractRelationships: true
-})
-
-console.log(`Imported ${result.stats.imported}/${result.stats.total} items`)
-console.log(`Created ${result.stats.relationships} relationships`)
-```
-
-**Features:**
-- 🧠 **AI Entity Detection** - Auto-detect entity types from data
-- 🔗 **Relationship Extraction** - Discover connections automatically
-- 📊 **Multi-Format Support** - CSV, JSON, YAML, text files
-- 🚀 **Batch Processing** - Efficient handling of large datasets
-- 💡 **Neural Analysis** - Confidence scoring and insights
-- 🎯 **Smart CSV Parsing** - Auto-delimiter detection
-- 🌐 **URL Imports** - Direct import from web sources
