feat(security): tune firewall to prioritize HITL 'Ask' over 'Deny' blocks

- Update security.ts to move all block patterns to ask status for better flow
- Bump version to 2.1.0
- Update README.md with missing config variables and documentation on HITL changes
- Adjust test suite to reflect 'ask' expectations

     *   **Network Exfiltration Block**: Prevents unauthorized data egress by blocking DNS-probing tools like `ping`, `dig`, `nslookup`, `nc`, and `wget`.
     *   **Shell Escape Defense**: Detects and blocks common shell escape bypasses like `find -exec` and `strings`.
     *   **Self-Modification Protection**: Locks core configuration files and the plugin's own source code from being modified by the agent.

+*   **Safe-by-Default (HITL)**: All potentially dangerous tool executions—including those matching the security firewall—require explicit human confirmation. The firewall has been tuned in v2.1.0 to prioritize human-in-the-loop (HITL) 'Ask' prompts over hard 'Deny' blocks to maintain agent flow. Auto-approval ("YOLO mode") is disabled unless the `PAI_I_AM_DANGEROUS=true` environment variable is set.
 *   **Terminal Sanitization**: Automatically strips ANSI escape codes from all logged output to prevent terminal-based attacks and ensure clean history.
 *   **Data Redaction**: Robustly masks secrets (AWS keys, GitHub tokens, Slack/Stripe/Google keys) in both logs and tool outputs.
