Release v0.6.0 patches multiple security vulnerabilities: it blocks code execution in the calculator tool via restricted parsing and AST validation, adds consent gating plus newline sanitization to cron, and redacts credentials from AWS responses.

Why it matters: Patch immediately to prevent remote code execution in calculator, mitigate unauthorized cron command injection, and stop credential leakage from AWS APIs.
