Remove Pivot/NetSuite attribution + the AI build-spec from the public repo

Drop the personal "I shipped the NetSuite integration at Pivot" claim from the
README and lib/erp.ts (kept the useful "swap fakeErp for a real adapter" point),
and delete PROMPT.md — the raw AI build-spec doesn't belong in a public showcase
repo (it also carried the bio claims). No secrets were ever committed (verified
full-history scan), so no history rewrite needed. Gates green.

 ### The fake ERP adapter
 
-[`lib/erp.ts`](lib/erp.ts) is a **stub with a real interface** — never a live ERP call. The reconciliation agent posts through an `ErpAdapter`; swap the `fakeErp` implementation for a `NetSuiteAdapter` of the same interface and the agent is unchanged. (For the record: I shipped the real NetSuite integration — the SuiteTalk vendor-bill + PO-match sync — at Pivot. This stub stands in for it so the public demo stays self-contained and side-effect-free.)
