feat: verb subtype + updateRelation + requireSubtype enforcement

Brings verbs to first-class parity with nouns. The 7.29.0 subtype primitive
shipped for entities only; this release ships the symmetric verb mirror plus
the enforcement layer for ensuring every entity AND every relationship has
both type AND subtype.

Layer V1 — verb subtype mirror
- HNSWVerbWithMetadata.subtype + STANDARD_VERB_FIELDS set + resolveVerbField()
- Relation<T>.subtype, RelateParams<T>.subtype, UpdateRelationParams<T> extended,
  GetRelationsParams.subtype, GraphConstraints.subtype (for find connected)
- relate() persists subtype on verbMetadata + GraphVerb + transaction ops
- getRelations({ type, subtype }) fast-path filter with set membership
- find({ connected: { via, subtype, depth } }) traversal filter (depth-1 on
  the JS path; explicit error on depth > 1 pointing at Cortex native)
- verbsToRelations + storage destructure sites surface subtype to top-level
- All three graph-index fast-path queries (getVerbsBySource/ByTarget) enrich
  with subtype from metadata

Layer V2 — updateRelation() closes a pre-7.30 gap
- New first-class verb update method (parallel to update() for nouns)
- Changes subtype/type/weight/confidence/data/metadata in place
- Re-indexes in graph adjacency when verb type changes; id preserved
- validateUpdateRelationParams enforces id + at-least-one-field-to-update

Layer V3 — verb subtype storage rollup
- verbSubtypeCountsByType: Map<number, Map<string, number>> on BaseStorage
- verbSubtypeByIdCache for self-heal during update/delete
- incrementVerbSubtypeCount + decrementVerbSubtypeCount maintain state
- loadVerbSubtypeStatistics + saveVerbSubtypeStatistics persist to
  _system/verb-subtype-statistics.json (mirrors noun-side shape)
- rebuildVerbSubtypeCounts for poison recovery / explicit repair
- getVerbSubtypeCountsByType accessor for the public counts API
- Wired into init() / flushCounts() / saveVerbMetadata / deleteVerbMetadata

Layer V4 — verb counts API + relationshipSubtypesOf
- brain.counts.byRelationshipSubtype(verb, subtype?) — O(1) breakdown or point
- brain.counts.topRelationshipSubtypes(verb, n) — top N by count
- brain.relationshipSubtypesOf(verb) — sorted distinct subtypes

Layer V5 — migrateField extended to verbs
- New entityKind?: 'noun' | 'verb' | 'both' option (default 'noun')
- Mirror verb iteration via storage.getVerbs() with same path semantics
- verbToRelationLike + buildRelationMigrationUpdate helpers project the
  storage verb shape onto the Entity<T>-shaped surface readPath understands
- Routes through new updateRelation() for the verb-side rewrite

Enforcement (opt-in in 7.30, default in 8.0)
- brain.requireSubtype(type, options) — unified API for NounType OR VerbType.
  Registers per-type rules with optional values whitelist; composes with the
  brain-wide flag.
- new Brainy({ requireSubtype: true }) — brain-wide strict mode. Every public
  write path validates the pairing guarantee.
- { except: [NounType.Thing, ...] } form for catch-all type exemptions
- Atomic-fail semantics on addMany / relateMany — pre-validate every item
  before any storage write, throw on first failure with item index
- Per-type rules + brain-wide flag both throw with descriptive messages
- VFS infrastructure bypass via metadata.isVFSEntity / isVFS markers so
  brain's own VFS writes don't get rejected when strict mode is on

VFS labeling — concrete subtypes for infrastructure entities
- VFS root: NounType.Collection + subtype: 'vfs-root' (was bare Collection)
- VFS directories: subtype: 'vfs-directory'
- VFS files: subtype: 'vfs-file' (NounType still mime-based)
- VFS containment edges: VerbType.Contains + subtype: 'vfs-contains'
- Lets consumers cleanly enumerate VFS state via find({ subtype: 'vfs-file' })
  and distinguish Brainy's VFS Collections from user-created Collections

Docs
- docs/guides/subtypes-and-facets.md extended with Layer V (Verbs) section +
  Enforcement section. New full reference at the bottom split into Layer 1
  (nouns), Layer V (verbs), Layer 2 (facets), Layer 3 (migration), Enforcement.
- docs/api/README.md adds updateRelation(), getRelations({ subtype }), the
  three verb-side counts methods, requireSubtype(), and the brain-wide
  constructor option. relate() params include subtype.
- docs/DATA_MODEL.md adds a Subtype-for-VerbType section + STANDARD_VERB_FIELDS
- docs/architecture/finite-type-system.md extends Principle 1a to verbs
- docs/QUERY_OPERATORS.md adds a verb-subtype filter section covering
  getRelations and find({connected, subtype}) traversal
- README.md "Subtypes" section now shows both noun + verb in one example +
  the enforcement APIs
- RELEASES.md v7.30.0 entry with the full noun/verb capability parity matrix

Tests
- tests/integration/verb-subtype-and-enforcement.test.ts — 30 new tests
  covering V1 round-trips, V1 set membership, updateRelation in place,
  updateRelation preservation, V2 counts breakdown + point + topN + distinct,
  V2 decrements on unrelate, V2 re-routes on updateRelation, V3 depth-1
  traversal filter, V3 depth>1 explicit error, V4 verb migration, V4 both
  entity kinds, V4 readBoth preservation, V5 per-type required rejection,
  V5 vocabulary rejection, V5 on-vocab acceptance, V5 verb-side enforcement,
  V5 addMany atomic-fail, V5 relateMany atomic-fail, V5 update enforcement,
  V5 updateRelation enforcement, V5 brain-wide strict mode, V5 except clause.

Internal 8.0 spec
- .strategy/BRAINY-8.0-SUBTYPE-CONTRACT.md (gitignored, not in npm artifact)
  documents the contract upgrade Cortex 3.0 implements against: required-by-
  default subtype, SubtypeRegistry typing hook, native simplification,
  multi-hop traversal native fast path, brain.fillSubtypes() migration helper.
  Coordinated via PLATFORM-HANDOFF rows CTX-SUBTYPE-PARITY-V2 (7.30 parallel
  work) and CTX-SUBTYPE-8.0-CONTRACT (8.0 spec).

### `updateRelation(params)``Promise<void>`
Update an existing relationship. Mirror of `update()` for verbs — closed a long-standing gap (verbs had no update path before 7.30).
```typescript
// Change the subtype on an existing relationship
await brain.updateRelation({ id: relId, subtype: 'dotted-line' })
// Update weight + confidence
await brain.updateRelation({ id: relId, weight: 0.7, confidence: 0.9 })
// Change verb type (re-indexes in graph adjacency, id preserved)
await brain.updateRelation({ id: relId, type: VerbType.WorksWith })
```
**Parameters:**
- `id`: `string` - Relationship ID (required)
- `type?`: `VerbType` - Change verb type (re-indexes in graph adjacency)
- `subtype?`: `string` - Change sub-classification (omit to preserve existing)
- `weight?`: `number` - New weight (0-1)
- `confidence?`: `number` - New confidence (0-1)
- `data?`: `any` - New content
- `metadata?`: `object` - Metadata to merge (or replace with `merge: false`)
- `merge?`: `boolean` - Merge or replace metadata (default: true)
**Returns:** `Promise<void>`

#### `counts.byRelationshipSubtype(verb, subtype?)``Record<string, number> | number`
Verb-side mirror of `counts.bySubtype`. O(1) per-VerbType-per-subtype counts.
```typescript
brain.counts.byRelationshipSubtype(VerbType.ReportsTo)
// → { direct: 12, 'dotted-line': 3 }
brain.counts.byRelationshipSubtype(VerbType.ReportsTo, 'direct')
// → 12
```
#### `counts.topRelationshipSubtypes(verb, n=10)``Array<[subtype, count]>`
Top N subtypes for a `VerbType` ranked by count.
```typescript
brain.counts.topRelationshipSubtypes(VerbType.ReportsTo, 3)
// → [['direct', 12], ['dotted-line', 3]]
```
#### `relationshipSubtypesOf(verb)``string[]`
Sorted distinct subtypes seen for a `VerbType`.
```typescript
brain.relationshipSubtypesOf(VerbType.ReportsTo)
// → ['direct', 'dotted-line']
```
#### `requireSubtype(type, options?)``void`
Register subtype enforcement for a specific `NounType` or `VerbType`. Unified API for nouns and verbs. Composes with the brain-wide `requireSubtype` constructor flag.
```typescript
// Lock down Person sub-classification
brain.requireSubtype(NounType.Person, {
values: ['employee', 'customer', 'vendor'],
required: true
})
// Lock down management edges
brain.requireSubtype(VerbType.ReportsTo, {
values: ['direct', 'dotted-line'],
required: true
})
```
**Parameters:**
- `type`: `NounType | VerbType` - The type to register
- `options.values?`: `string[]` - Vocabulary whitelist (rejects off-vocab values)
- `options.required?`: `boolean` - Whether subtype is required (default: `true`)
#### Brain-wide strict mode — `new Brainy({ requireSubtype })`
Constructor option that enforces subtype on every `add()` / `addMany()` / `update()` / `relate()` / `relateMany()` / `updateRelation()` for every type:
```typescript
// Every write must include subtype
const brain = new Brainy({ requireSubtype: true })
// Exempt specific types (e.g. catch-all Thing)
const brain2 = new Brainy({
requireSubtype: { except: [NounType.Thing, NounType.Custom] }
})
```
When strict mode is on:
- Every public write path checks the pairing guarantee.
- `addMany()` / `relateMany()` validate all items BEFORE any storage write — atomic-fail, no partial writes.
- Brainy's own VFS infrastructure writes bypass via the `metadata.isVFSEntity: true` marker.
- Per-type registrations always apply regardless of the brain-wide flag.
Becomes the default in 8.0.0.
#### `trackField(name, options?)``void`
Register a metadata field for cardinality + per-NounType breakdown stats. With `values: [...]`, validates against the whitelist on `add()`/`update()`.
