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
