/**
 * In-memory wallet roster shared by `ByokKeyring` and `ServerKeyring`.
 *
 * Lookup keys:
 *   - `id` (optional per entry) — unique within the directory
 *   - `(namespace, address)` — composite key, normalized by the caller-supplied
 *     `addressKey` (local: namespace-scoped lowercase EVM; server: plain
 *     lowercase). Wallets without a namespace use `undefined` for the namespace
 *     slot.
 *   - `name` — linear scan (small N expected; lookup is rare relative to read)
 *
 * Returned values are shallow clones, so callers cannot mutate the directory
 * through them.
