v0.3.6 — Crash detection & findings analyzer

This release expands the fuzzer to detect and report many classes of MCP-server software issues, not just protocol/transport errors.

Highlights

• Server-crash detection (segfault/abort/panic / non-zero exit) with stderr capture and per-crash reproductions
• Post-run findings analyzer: auth_bypass, injection_reflection, oversized_response, hang, internal_error, error_leakage, memory_growth, non_determinism, accepted_malformed, performance_outlier
• Findings written to <output-dir>/findings.json; crash repros under <output-dir>/crashes/
