feat(client): generic shared-wallet shim surface (docs/storeRegistry/isolation/accounts)

Port the shared-wallet shim mechanics from the Festipod app into the
generic @ng-eventually/client library — zero app-specific knowledge, the
consumer injects the domain (entity->scope mapping, connections, storage).

New namespaces exposed from src/index.ts:
- docs      docCreate/sparqlUpdate/sparqlQuery via the REAL injected `ng`
            (getConfig().ng), never the public makeNg proxy — the JS-over-
            iframe double proxy breaks doc_create postMessage marshaling
            (DataCloneError). Validated hard constraint.
- storeRegistry  generic (account,scope)->NURI resolver, createEntityDoc/
            listEntityDocs + per-scope index, sharedWalletShim in the
            private_store, cache. Consumer wiring injected via
            configureStoreRegistry({ getSession, normalizeUser }).
- isolation  pure applyIsolation (public=all / protected=owner+connections
            / private=owner); accessors + connection graph injected.
- accounts  AccountStore (localStorage-backed faux login, storage injected)
            + normalizeUsername. React wrapper intentionally NOT ported.

polyfill.ts gains configureStoreRegistry/getStoreRegistryDeps + resetConfig.
36/36 bun test, tsc --noEmit rc=0.

/**

* STOPGAP — part of the shared-wallet shim. The real NextGraph login (redirect
* to the broker, opening the single SHARED wallet) is perceived as a technical
* access barrier, not as a login. THIS layer is the perceived login: the user
* picks a username (no password — declarative), persisted in `localStorage` so
* the "session" survives reloads and lands on the same account when the shared
* wallet re-opens.
*
* `login()` / `logout()` here are FAUX: they only read/write the username in
* storage. They must NEVER call NextGraph (no session_stop / wallet_close) — the
* shared wallet stays open underneath. The real logout lives elsewhere.
*
* FRAMEWORK-AGNOSTIC on purpose: NO React, no DOM assumption beyond an optional
* storage. The React `Context`/`Provider` is a thin wrapper that stays in the
* consumer app (it wires `useState` around {@link login}/{@link logout}). The
* lib must not force a React dependency. Removed at migration.

/**
* isolation — APPLICATION-LAYER visibility filter, per **account + connections**.
*
* STOPGAP (shared-wallet shim): with one shared wallet everything is physically
* readable. To make staging *behave* like the target infra, the consumer HONORS
* a visibility matrix by filtering reads relative to the current principal and
* its social connections:
*
* - public → visible to everyone
* - protected → visible to the owner + its direct connections
* - private → visible to the owner only
*
* Pure functions — no NextGraph, no React, ZERO application domain. The consumer
* supplies (a) the connection graph (who is connected to whom — the lib does NOT
* invent it) and (b) accessors telling, for each item, its owner and scope.
*
* ── isolation vs ReadCap (read-filter.ts / caps.ts) — they COEXIST ──────────
* Two DIFFERENT axes, deliberately kept separate:
*
* ReadCap ({@link ./caps} + {@link ./read-filter})
* - Unit : the DOCUMENT (an item's `@graph` = the repo it lives in).
* - Question: does the current principal HOLD this document's read cap?
* - Models : NextGraph's native capability delivery (broker-enforced).
* - Grants : explicit, per-document (grantRead / makePublic).
*
* isolation (this file)
* - Unit : the ITEM / record (per owner + scope).
* - Question: given WHO is connected to WHOM, may this principal see it?
* - Models : an application social-visibility policy, above the doc layer.
* - Grants : implicit, derived from the connection graph + the item's scope.
*
* They are NOT redundant and do NOT merge: ReadCap answers "can the wallet even
* fetch this document"; isolation answers "should the app show this record to
* this account given its relationships". The connection-derived `protected`
* visibility of isolation has no equivalent in the per-document cap model. Both
* are removable scaffolds; each disappears against a different piece of the real
* infra (caps → native ReadCaps; isolation → real per-account social graph +
* per-account wallets). See T01.c ## Result for the recorded decision.

/**
* storeRegistry — resolves (account, scope) → document NURI.
*
* **STOPGAP / polyfill-era.** Emulates the target infrastructure — where each
* user owns their own public/protected/private stores — on top of ONE shared
* wallet. It creates one document per (account × scope) inside that shared
* wallet (via the `docs.docCreate` primitive), so the `scope`
* (`public|protected|private`) is a LOGICAL attribute tracked here, NOT a
* physical NextGraph store. Isolation is enforced by the app layer + the
* emulated cap registry, not by crypto.
*
* The mapping (account → its 3 document NURIs) is the **sharedWalletShim**,
* persisted as RDF in the shared wallet's private store (the anchor, always
* known from the session). That makes login cross-device: another device
* opening the same wallet reads the same shim and finds the same accounts.
*
* ── GENERIC by construction ──────────────────────────────────────────────
* This module knows ONLY the three native scopes. It does NOT know any
* application entity kind (event, meeting-point, profile, …). The consumer
* maps its entities to a scope and calls `createEntityDoc(scope)` /
* `listEntityDocs(scope)` with the resulting native scope. Zero domain here.
*
* ── WHAT DISAPPEARS AT MIGRATION ─────────────────────────────────────────
* At the real multi-store migration the shim vanishes entirely: `(account,
* scope)` maps to the user's REAL store NURI instead of a document in the
* shared wallet, `docCreate` targets the real per-user store, and the
* per-scope index document (the store-container emulation) is replaced by the
* store itself. The consumer-facing surface (`createEntityDoc`,
* `listEntityDocs`, resolvers) is designed to survive that swap unchanged.
*
* All NextGraph I/O routes through the T01.a `docs` primitive (real injected
* `ng`), so this module imports **no** `@ng-org` package.
