v0.4.2 — zero-config scan, 5 framework adapters, hardening

Zero-config testing, framework integrations, and a hardening pass. Everything additive.

Highlights

• faultline scan my_agent.py:agent — zero-config: discovers your wrapped tools, breaks them, gates CI. Plus faultline doctor (preflight) and faultline init (scaffold a suite + CI workflow).
• One-line framework integration: fl.instrument(...) for LangGraph, LangChain, LlamaIndex, pydantic-ai, crewAI — each verified against the real installed library.
• fl.tools_really_called([...]) — catches an agent answering from a tool it never actually called.
• replay(transform=...) — catches silent behavioral drift after a context change.
• fl.assert_resilient(agent, task) — drop into any pytest/unittest suite.
• scan --explain — shows exactly what was corrupted and why each FAIL.
• Hardening from 3 adversarial passes (intermittent silent failures now gate; $6,000-style figures now detected; Decimal money values now corruptible).
