fix: exclude __words__ keyword index from corruption detection and getStats()

The __words__ keyword index stores 50-5000 entries per entity (one per
word), which inflated avg entries/entity well above the corruption
threshold of 100. This caused:

1. validateConsistency() to falsely detect corruption on every startup,
   triggering unnecessary clearAllIndexData() + rebuild() cycles
2. getStats() to log false "Metadata index may be corrupted" warnings
   and report inflated totalEntries/totalIds stats

Both methods now skip __words__ when counting, so stats and health
checks reflect metadata fields only (noun, type, createdAt, etc.).
Keyword search is unaffected since the __words__ field index itself
is not modified.

## v4.0.0 Augmentation Architecture
## Augmentation Architecture
### Key Improvements for Billion-Scale Performance
1. **Metadata/Vector Separation**: Augmentations now work with separated metadata and vectors
- Metadata stored separately from vector data
- 99.2% memory reduction for type tracking
- Two-file storage pattern for optimal I/O
- Metadata stored separately from vector data
- 99.2% memory reduction for type tracking
- Two-file storage pattern for optimal I/O
2. **Type System Enforcement**: All metadata requires type fields
- `NounMetadata` requires `noun: NounType`
- `VerbMetadata` requires `verb: VerbType`
- Type inference system available as public API
- `NounMetadata` requires `noun: NounType`
- `VerbMetadata` requires `verb: VerbType`
- Type inference system available as public API
3. **Storage Adapter Pattern**: Internal vs public method distinction
- `_methods`: Return pure structures (HNSWNoun, HNSWVerb)
- Public methods: Return WithMetadata types
- MetadataEnforcer Proxy ensures proper access
- `_methods`: Return pure structures (HNSWNoun, HNSWVerb)
- Public methods: Return WithMetadata types

### What This Means for Augmentation Users
**✅ If you use built-in augmentations**: No changes needed! They're all updated for v4.0.0.

### 3. Encryption Augmentation
```typescript
class EncryptionAugmentation extends BaseAugmentation {
readonly name = 'encryption'
readonly timing = 'both' as const
readonly operations = ['add', 'get'] as const
readonly priority = 90 // Run early
async execute<T>(operation: string, params: any): Promise<any> {
if (operation === 'add') {
// Encrypt before storing
if (params.metadata?.sensitive) {
params.content = await this.encrypt(params.content)
params.encrypted = true
}
return params
}
readonly name = 'encryption'
readonly timing = 'both' as const
readonly operations = ['add', 'get'] as const
readonly priority = 90 // Run early
if (operation === 'get' && params.result?.encrypted) {
// Decrypt after retrieval
params.result.content = await this.decrypt(params.result.content)
delete params.result.encrypted
return params.result
}
}
async execute<T>(operation: string, params: any): Promise<any> {

### 3. Handle Errors Gracefully
```typescript
async execute<T>(operation: string, params: any): Promise<void> {
try {
await this.riskyOperation()
} catch (error) {
// Log but don't break the main operation
console.error(`Augmentation error in ${this.name}:`, error)

// Optionally report to monitoring

}
```
### 4. Be Performance Conscious
```typescript
class CachedAugmentation extends BaseAugmentation {
private cache = new Map<string, any>()
async execute<T>(operation: string, params: any): Promise<any> {
const key = this.getCacheKey(params)
// Check cache first
if (this.cache.has(key)) {
return this.cache.get(key)
}
// Expensive operation
const result = await this.expensiveOperation(params)
this.cache.set(key, result)
return result
}
private cache = new Map<string, any>()
async execute<T>(operation: string, params: any): Promise<any> {
const key = this.getCacheKey(params)
// Check cache first
if (this.cache.has(key)) {
return this.cache.get(key)
}
// Expensive operation
const result = await this.expensiveOperation(params)
this.cache.set(key, result)
return result
}
}
```
### 5. Clean Up Resources
```typescript
protected async onShutdown(): Promise<void> {
// Close connections
await this.connection?.close()
// Clear intervals
clearInterval(this.interval)
// Flush buffers
await this.flush()
// Clear caches
this.cache.clear()
// Close connections
await this.connection?.close()
// Clear intervals
clearInterval(this.interval)
// Flush buffers
await this.flush()
// Clear caches
this.cache.clear()
}
