Sylvain Duchesne bf753770b8 feat(client): real per-document isolation + bilateral connections + deposit guards
The ReadCap filter now enforces on per-entity documents (consumers create one doc
per entity, so each has a declared policy — private→owner, protected→owner+
connections, public→all). Isolation is genuinely active, not dormant.

- connections.ts (new): a BILATERAL connection registry — a link grants protected
  read only when BOTH sides have asserted it (each assertion bound to its author).
  A unilateral/self-declared connection grants nothing (closes the confused-deputy
  hole). declareConnections is authenticated to the current identity.
- inbox.post: `from` is bound to the current identity — a spoofed `from` throws.
- discovery.submitToIndex: PUBLIC-ONLY — a governed non-public doc is refused
  (no protected/private leak into the world-readable index).
- docs/simulation.md: documents this as application-level emulated isolation on a
  shared wallet (not crypto); at NextGraph maturity → real caps, consumer unchanged.

89 tests pass (+10 covering: active protected isolation via bilateral connect,
unilateral grants nothing, from-spoof rejected, non-public submit refused). tsc rc=0.

Sylvain Duchesne d804a436d7 feat(client): inbox mechanism, write-guard, SPARQL injection hardening
Polyfill capabilities landed for Festipod's T02 features (all generic,
zero-domain — the consumer injects the domain).

- inbox: implement the previously-stubbed namespace. post(target,{from?,
  payload,ts?}) deposits {from,payload,ts} as RDF via docs.sparqlUpdate (the
  real injected ng, never makeNg); read/materialize + watch emulate the curator
  in-lib (deposits read via docs.sparqlQuery). `from` optional = anonymity.
- write-guard: caps.hasWritePolicy() + ng-proxy.sparql_update rejects when the
  target doc is under a write policy and the current user lacks its write cap;
  passthrough otherwise (no regression). Read-cap registry unchanged.
- sparql.ts (new): escapeLiteral / escapeIri / assertNuri, exported from index.
  store-registry now escapes every literal and validates/encodes every IRI-
  position value — closes a SPARQL-injection hole where an untrusted username
  could inject triples into the shim (the account→doc-NURI trust root).

Tests: inbox, sparql (incl. injection), ng-proxy write-guard, isolation-active.
68 tests pass; tsc --noEmit rc=0.
