feat(llm-security-copilot): port llm-security v5.1.0 to GitHub Copilot CLI
Full port of llm-security plugin for internal use on Windows with GitHub Copilot CLI. Protocol translation layer (copilot-hook-runner.mjs) normalizes Copilot camelCase I/O to Claude Code snake_case format — all original hook scripts run unmodified. - 8 hooks with protocol translation (stdin/stdout/exit code) - 18 SKILL.md skills (Agent Skills Open Standard) - 6 .agent.md agent definitions - 20 scanners + 14 scanner lib modules (unchanged) - 14 knowledge files (unchanged) - 39 test files including copilot-port-verify.mjs (17 tests) - Windows-ready: node:path, os.tmpdir(), process.execPath, no bash Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
