- Add INTENT.md (purpose and inviolable principles) and SCOPE.md
(current operational boundary), matching the binect-js house style.
- Reconcile the PRD with the shipped document-lifecycle scope: add
ordering/server-sync requirements (4.3a), split the proxy queue vs.
tracking-log caps (4.6.3), and update the solution summary/closing.
- Rename computeMD5 -> computeContentFingerprint to be honest: it is a
fast sampled non-cryptographic fingerprint for dedup, not MD5.
