chore(memory): consolidate scattered feedback/project/reference files

Compressed memory store 104 -> 71 files via four passes:

- Syncro: 19 scattered feedback_syncro_* files merged into 3 rule files
  (api/billing/workflow) + an on-demand feedback_syncro_history.md for
  incident detail, quotes, and tech/product ID tables.
- Four near-duplicate merges: Howard paste-safety, Pluto build server,
  Howard backend deferral, IX server access (ssh+tailscale).
- Per-cluster rule/state/history split applied to GuruConnect (2->1),
  Dataforth (3->2), Cascades (7->3), GuruRMM (13->3).
- New reference_resource_map.md: single auto-loaded cheatsheet for
  "do I have access to X and how do I connect from this machine?"
- MEMORY.md rewritten to match the new layout.

Health: broken backlinks 8->7, overlap clusters 12->5, orphans 17->0.

-description: Cascades of Tucson department migration plan — Syncro ticket, plan file location, resume command
-metadata:
-  type: project
----
-
-Active multi-day migration project for Cascades of Tucson. Department-by-department domain join, folder redirection, and Entra sync rollout.
-
-**Why:** Full migration from workgroup/cloud-only to domain-integrated environment with clean end state (everything works automatically on fresh machine domain join).
-
-**Syncro ticket:** https://computerguru.syncromsp.com/tickets/110680053 — update with notes after each session.
-
-**Plan file:** `C:\Users\Howard\.claude\plans\wise-discovering-panda.md`
-
-[VERIFY 2026-05-26 — plan-file path C:\Users\Howard\... is machine-specific (Howard's box); confirm it resolves on ACG-TECH03L/Howard-Home or relocate the plan into the synced repo. Cascades m365-rollout still active/blocked.]
-
-**Resume command:** Howard says "resume the Cascades migration plan" → read plan file, check CURRENT SAVE POINT section, pick up at next unchecked item.
-
-**How to apply:** At every Cascades session start, read the plan file CURRENT SAVE POINT before doing any work. Update the save point and run /save at end of session.
