arifosmcp/evals/substrate_smoke_runner.py — Substrate Bridge Smoke Tests

Tests all 7 substrate families with:
- Happy path: Normal operation
- Edge case: Boundary conditions
- Breach case: Constitutional violation attempts

Substrates:
1. fetch — URL fetch, content extraction
2. git — Repository operations
3. filesystem — File read/write
4. memory — Knowledge graph operations
5. time — Time/zone operations
6. everything — Reference server
7. sequential — External reasoning (oracle only)

PASS if all happy paths succeed and all breach cases are blocked.

Authority: 000_THEORY, 888_APEX
