v0.1.3 — Import Graph + Cost Estimates

What's New

✨ Import Graph Analysis

• ctxeng now automatically pulls in locally imported Python modules
• If auth.py is relevant, files it imports get included automatically
• Configurable depth (default: 1 hop) and score decay (default: 0.7)
• Works via static AST parsing — no runtime execution
• New API: build_import_graph(), expand_with_imports()
• New CLI flags: --import-graph-depth N, --no-import-graph

💰 Cost Estimates

• ctx.cost_estimate shows rough USD input cost for known models
• Shown automatically in ctx.summary():
  Est. cost: ~$0.037 (claude-sonnet-4)
• New public API: estimate_cost(tokens, model)
• New CLI flag: --no-show-cost to hide from output
• Supported: Claude, GPT-4o, GPT-4, Gemini, Llama
