feat(security-sidecar): implement a security tooling sidecar with tiered installer and protocol

- Add `zesdex_sec_daemon` module with main entry point for running the security daemon.
- Implement `TieredInstaller` for installing security tools from various sources (pip, binaries, gems).
- Create a newline-delimited JSON frame protocol for communication between the daemon and tools.
- Introduce a `ToolRegistry` for managing and dispatching tool executions.
- Add various tools including HTTP, SQLMap, Nuclei, and more with their respective execution logic.
- Establish health check and installation commands for tool management.
- Include prompts for classifier and quality reviewer to enhance code review and safety checks.
- Document the system's tools and guidelines for usage.
