feat: redact sensitive credentials from command logs

Add redaction of sensitive environment variables and credentials from
logged command output to prevent leaks to log aggregators (Datadog,
CloudWatch, etc.).

Changes:
- Import redact_text_secrets utility in execute_command
- Apply redaction to formatted command string before logging
- Add 4 comprehensive tests for redaction behavior

The existing redact_text_secrets utility handles:
- API keys (OpenAI, Anthropic, HuggingFace, Together, OpenRouter)
- Bearer tokens and session tokens
- GitHub, GitLab, Slack tokens
- Environment variables matching SECRET_KEY_PATTERNS
- URL query parameters with sensitive values
