+ * Codebase-wide prompt injection scan
+ *
+ * This test suite scans all files that become part of LLM agent context
+ * (agents, workflows, commands, planning templates) for prompt injection patterns.
+ * Run as part of CI to catch injection attempts in PRs before they merge.
+ *
+ * What this catches:
+ *   - Instruction override attempts ("ignore previous instructions")
+ *   - Role manipulation ("you are now a...")
+ *   - System prompt extraction ("reveal your prompt")
+ *   - Fake system/assistant/user boundaries (<system>, [INST], etc.)
+ *   - Invisible Unicode that could hide instructions
+ *   - Exfiltration attempts (curl/fetch to external URLs)
+ *
+ * What this does NOT catch:
+ *   - Subtle semantic manipulation (requires human review)
+ *   - Novel injection techniques not in the pattern list
+ *   - Injection via legitimate-looking documentation
+ *
+ * False positives: Files that legitimately discuss prompt injection (like
+ * security documentation) may trigger warnings. The allowlist below
