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: Syncro emergency/after-hours billing — check prepay_hours first
-description: Emergency labor is time-and-a-half (×1.5), applied once, never additive. Branch by customer.prepay_hours. Prepaid → emergency item 26184 at hours×1.5 (premium in quantity); non-prepaid → 26184 at actual hours (rate has 1.5×).

-**Rule:** Before adding any Emergency/after-hours labor line on a Syncro ticket, `GET /customers/<id>` and read `prepay_hours`. Emergency = **time-and-a-half (×1.5), applied ONCE** — never bill a separate regular line + emergency line for the same hours.
-
-- **No prepaid block (`prepay_hours == 0`):** product `26184` (Labor - Emergency or After Hours) at quantity = **actual hours**, and set `price_retail` by the work's **delivery channel** (the 1.5× lives in the dollars — do NOT also ×1.5 the quantity): **Onsite emergency = $262.50** (175 × 1.5; this is 26184's default rate); **Remote / In-Shop emergency = $225** (150 × 1.5) → override `price_retail` to `225`. Fetch the base rate live and ×1.5 if unsure.
-- **Prepaid block (`prepay_hours > 0`):** product `26184` at quantity = **actual hours × 1.5** (hours + 50%). Prepaid blocks debit by QUANTITY not dollars, so the 1.5× premium goes in the **quantity**; the invoice nets to $0 and the block debits hours×1.5. e.g. 1.5 emergency hrs → `26184` @ **2.25**. (Delivery channel / dollar rate is **irrelevant** for prepaid — only the quantity hrs×1.5 matters.)
-
-**(Updated 2026-05-27 — Mike):** prepaid emergency now uses the **emergency item `26184`** at ×1.5 quantity — this REPLACES the old "prepaid → onsite `26118` at ×1.5." Using 26184 labels the line correctly as emergency and maps right in QuickBooks; the dollar double-1.5 worry doesn't apply to prepaid since the invoice is $0. Reaffirmed on #32332 (Cascades, prepaid 27h): total 1.5 emergency hrs → `26184` @ 2.25 (Howard had split it into made-up onsite/emergency lines).
-
-**Why ×1.5-not-additive:** Learned on #32203 (Desert Auto Tech) 2026-04-23 — billing "1h onsite + 1h emergency" as two additive lines came out $437.50 when 1 actual hour of emergency should bill at time-and-a-half. Emergency IS time-and-a-half; one line.
-
-**How to apply:**
-- Every emergency/after-hours bill: check `prepay_hours` BEFORE choosing the quantity. One emergency line on `26184`.
-- Always set `price_retail` explicitly (fetch live via `GET /products/26184`); the rate doesn't auto-populate and the line posts $0 if omitted.
-- Use the product's REAL name on the line (work detail goes in the description) — see [[feedback-syncro-no-madeup-labor-items]].
-- Verify after invoicing: `.invoice.total` (non-prepaid) or the prepay-block decrement (prepaid).
