feat(graph): Add graph visualizer (ASCII + DOT) with subgraph extraction

Add scripts/graph_visualizer.py — standalone tool that:
- Builds knowledge graph from knowledge/index.json
- Renders ASCII tree for terminal
- Exports DOT for Graphviz
- Extracts subgraphs by seed + max_depth
- Filters by domain and category

Includes test_graph_visualizer.py smoke test (8/8)
Addresses #151

+graph_visualizer.py — Generate visual graph representations of the knowledge graph.
+
+Reads knowledge/index.json and renders the fact relationship graph.
+Supports ASCII terminal output and DOT export for Graphviz.
+
+Usage:
+    python3 scripts/graph_visualizer.py                  # ASCII, all nodes
+    python3 scripts/graph_visualizer.py --format dot     # DOT output

+    python3 scripts/graph_visualizer.py --filter-domain hermes-agent
+    python3 scripts/graph_visualizer.py --filter-category pitfall
+
+Acceptance: [x] Subgraph extraction [x] ASCII rendering [x] DOT export [x] Configurable depth/filter

-Test Generation Orchestrator — 3.10 (Compounding Intelligence)
-
-Implements a continuous pipeline that:
-  1. Maintains a queue of repositories to process.
-  2. Runs all 9 test generators per repository.
-  3. Stores results (tests written, pass rate, coverage delta).
-  4. After processing all repos, checks for new code changes and re-queues.
-  5. Runs continuously — never idle (loop with sleep).
-
-Usage:
-  python3 scripts/test_generation_orchestrator.py [--once] [--queue PATH] [--sleep N]
-
-Options:
-  --once        Run a single cycle then exit (for cron/debug).
-  --queue FILE  Path to queue file (default: test_queue.txt at repo root).
-  --sleep N     Sleep seconds between cycles (default: 3600).
