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.

-name: Mac gururmm hook setup pending
-description: Mikes-MacBook-Air needs install-hooks.sh run in gururmm repo — one-time setup to prevent sqlx migration drift
-type: project
----
-
-[CONFIRMED PENDING 2026-05-27 — Mac session verified install-hooks.sh has NOT been run on Mikes-MacBook-Air: the gururmm submodule is initialized but only default .sample hooks are present. Action genuinely still open — keep this file; run install-hooks.sh on the Mac before gururmm dev there.]
-
-The gururmm repo on this Mac needs a one-time setup step that was applied to all other machines on 2026-04-19.
-
-**Action required (do this now, before any gururmm work):**
-
-```bash
-cd /Users/azcomputerguru/ClaudeTools/projects/msp-tools/guru-rmm
-git pull
-bash scripts/install-hooks.sh
-```
-
-**What this does:**
-- Sets `core.hooksPath = scripts/hooks/` so the pre-commit CRLF check is active
-- Sets `core.autocrlf=false` and `core.eol=lf` locally and globally
-- Prevents sqlx migration checksum drift (root cause: CRLF vs LF sha384 mismatch)
-
-**Why:** The gururmm build server refused to start after a rebuild because migration file hashes differed between what was stored in `_sqlx_migrations` and the current files. Root cause was CRLF line endings from Windows commits. Fixed with `.gitattributes` + per-machine git config. This command applies the git config side.
-
-macOS defaults to LF, so this is low-risk — mainly sets the hooksPath so the pre-commit guard is active.
-
-**After running:** Delete this memory file or mark it resolved.
