- :journal-inmemory — added iosX64/iosArm64/iosSimulatorArm64 to the
target set so :storage-inmemory (which now depends on it) can build
for iOS. Pure `MutableMap`+`Mutex` impl, no I/O, fully portable.
- client/README.md — new «Кэш списка бесед» section:
- shows `agent.conversationStore` as the read-only entry point;
- demonstrates the «remote.listFlow → local.upsert + outbox.agentEvents
→ local apply» pattern (Created/Renamed/Touched/Deleted);
- notes that the cache is built into `AgentikAgent` by default;
- mentions `wrapWithLocalConversationCache` for custom stores (SQLite/JSON);
- points to `agentikHttpClient(...).raw` as the escape-hatch for clients
that want direct HTTP.
Also adds `HttpConversationStore.kt` to the index (the file existed on
disk but wasn't `git add`ed in the previous commit).
