# T-735: Remove dead _build_graph function from fabric.py

## Context

`_build_graph()` was used by the old Cytoscape `/fabric/graph` route. The D3 Fabric Explorer (T-730) builds graphs client-side. Function is dead code (82 lines).

## Acceptance Criteria

### Agent
- [x] `_build_graph` function removed from fabric.py
- [x] fabric.py still passes syntax check
- [x] Vendor copy synced
- [x] All fabric routes still work

## Verification

python3 -c "import ast; ast.parse(open('web/blueprints/fabric.py').read())"
! grep -q "_build_graph" web/blueprints/fabric.py
grep -qm1 "Fabric Explorer" <(curl -s http://localhost:3000/fabric/graph)
