- Purges any existing Node artifacts (package.json, node_modules) ensuring a pristine Deno + Rust environment.
- Refactors Gen 2 Proof of Concepts (cfg, code_intelligence, protobuf, tool_sandbox) to execute external tools (tree-sitter, semgrep, protoc) as native system commands using Deno.Command.
- Introduces `sys_exec.ts` to handle pre-flight dependency checks, ensuring scripts fail gracefully rather than breaking when a required host tool is missing.
