fix: resolve getRelations() empty array bug and add string ID shorthand

**Problem**: brain.getRelations() returned empty array when called without
parameters, making 524 imported relationships inaccessible for Workshop team.

**Root Cause**: Method only queried storage when `from` or `to` parameters
were provided. Without params, it returned empty array.

**Solution**:
- Add support for "get all" via storage.getVerbs() when no from/to provided
- Add string ID shorthand: getRelations(id) → getRelations({ from: id })
- Default limit: 100 (matching storage layer pattern)
- Production safety: warn for >10k queries without filters
- Fix broken improvedNeuralAPI.ts calls (getVerbsForNoun → getRelations)
- Fix property bugs: verb.target → verb.to, verb.verb → verb.type

**Testing**:
- 14 new integration tests covering all query patterns
- All critical tests passing (25/25)
- Backward compatible - no breaking changes

**Impact**: Resolves Workshop bug where imported relationships were invisible

/**
* Get relationships
* Get relationships between entities
*
* Supports multiple query patterns:
* - No parameters: Returns all relationships (paginated, default limit: 100)
* - String ID: Returns relationships from that entity (shorthand for { from: id })
* - Parameters object: Fine-grained filtering and pagination
*
* @param paramsOrId - Optional string ID or parameters object
* @returns Promise resolving to array of relationships
*
* @example
* ```typescript
* // Get all relationships (first 100)
* const all = await brain.getRelations()
*
* // Get relationships from specific entity (shorthand syntax)
* const fromEntity = await brain.getRelations(entityId)
*
* // Get relationships with filters
* const filtered = await brain.getRelations({
* type: VerbType.FriendOf,
* limit: 50
* })
*
* // Pagination
* const page2 = await brain.getRelations({ offset: 100, limit: 100 })
* ```
*
* @since v4.1.3 - Fixed bug where calling without parameters returned empty array
* @since v4.1.3 - Added string ID shorthand syntax: getRelations(id)
