Replace dynamic agent log entries with fixed phrases to prevent data leakage Description

[shahabmohi]

In lib/sandbox/agents/cursor.ts (e.g., lines 16, 21, 25 and elsewhere), dynamic values (redacted command, stdout, stderr) are passed into TaskLogger. Even with the redaction helper, any miss or partial redaction can leak sensitive data. The Gemini agent follows the same pattern (e.g., lib/sandbox/agents/gemini.ts:22, 281).

Required change:

• Replace all TaskLogger calls that include dynamic command/output content with fixed, non-variable phrases (e.g., “Command executed”, “Agent produced output”, “Agent error occurred”).
• Add tests (or a lint rule) to prevent reintroduction of dynamic content in user-facing logs.
