Add universal agent operating principles (AGENTS.md)

[devin-ai-integration]

Adds the universal Garza OS agent operating principles (skills-first, plan-first, composite tools, Fabric AI memory, test+debug plan, Claude Code delegation) so this repos Capy project auto-syncs the principles into Settings → Context.

No code changes, no secrets. Same portable version already merged into garza-home, jaden-health-intelligence, garza-school-hub, proton-unified-mcp, garza-os-github, and garza-jett-activity-agent.

Code Review Summary

Status: No Issues Found | Recommendation: Merge

Files Reviewed (1 file)

• AGENTS.md — new documentation file, no code changes

---

Notes:

• Pure documentation addition; no executable code, secrets, or logic to audit.
• Content is internally consistent: each principle references a named skill (default-workflow, composite-tools, fabric-memory, dev-with-claude-code) that agents should be able to resolve at runtime.
• The external URL on line 34 (https://api.fabric.so) is hardcoded in a prose instruction file — acceptable here, but ensure the Fabric endpoint is stable or update this file if it changes.
• The itsablabla project name on line 3 matches the repo org, confirming this is the correct portable copy for this repo.
