memory + rmm: agy-headless correction, gemini errorlog, bump guru-rmm (Syncro recon + spec plan)

- memory: agy.exe NOW works headless (v1.0.6+ --print/-p, --add-dir) — corrected
  reference_antigravity_agy_not_headless + MEMORY.md index; supersedes the old "DOA headless" note.
- errorlog: gemini-cli OAuth eligibility failure on this machine (agy/ask-gemini).
- bump projects/msp-tools/guru-rmm -> a7ecb9f (RMM_THOUGHTS Feature 11 OS Updates + RMM Fixes batch;
  docs/recon + docs/specs: Syncro policy/device recon + policy-redesign spec plan).
