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

### [4.1.3](https://github.com/soulcraftlabs/brainy/compare/v4.1.2...v4.1.3) (2025-10-21)
### 🐛 Bug Fixes
* **api**: fix getRelations() returning empty array when called without parameters
- Fixed critical bug where `brain.getRelations()` returned `[]` instead of all relationships
- Added support for retrieving all relationships with pagination (default limit: 100)
- Added string ID shorthand syntax: `brain.getRelations(entityId)` as alias for `brain.getRelations({ from: entityId })`
- Production safety: Warns when fetching >10k relationships without filters
- Fixed broken method calls in improvedNeuralAPI.ts (replaced non-existent `getVerbsForNoun` with `getRelations`)
- Fixed property access bugs: `verb.target``verb.to`, `verb.verb``verb.type`
- Added comprehensive integration tests (14 tests covering all query patterns)
- Updated JSDoc documentation with usage examples
- **Impact**: Resolves Workshop team bug where 524 imported relationships were inaccessible
- **Breaking**: None - fully backward compatible
### [4.1.2](https://github.com/soulcraftlabs/brainy/compare/v4.1.1...v4.1.2) (2025-10-21)

* 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)
