docs(plan): correct CMake target name and createCollection signature

Locally installed libsmartbotic-db-client-dev 1.7.1 exports
smartbotic::db-client (not smartbotic::database::client) and its
Client::createCollection takes flat params (name, defaultTtlSeconds,
encrypted, maxVersions, vectorDimension), not a CollectionOptions struct.
Updated the adapter code in Task A5 accordingly.

 Insert near the other `find_package` calls (top of CMakeLists, before `smartbotic_storage` definition). Use a fallback chain so we work whether the upstream ships CMake config or only pkg-config:
 
 ```cmake
-# Upstream smartbotic-database client library
-find_package(smartbotic-db-client CONFIG QUIET)
-if(NOT smartbotic-db-client_FOUND)
-    find_package(PkgConfig REQUIRED)
-    pkg_check_modules(SMARTBOTIC_DB_CLIENT REQUIRED IMPORTED_TARGET smartbotic-db-client)
-    add_library(smartbotic::database::client ALIAS PkgConfig::SMARTBOTIC_DB_CLIENT)
-endif()
+# Upstream smartbotic-database client library — provides target smartbotic::db-client
+find_package(smartbotic-db-client CONFIG REQUIRED)
 ```
 
-If Task A2 Step 3 revealed a different target name, substitute it everywhere in this plan.
+(Verified locally: `/usr/lib/x86_64-linux-gnu/cmake/smartbotic-db-client/smartbotic-db-clientConfig.cmake` exports `smartbotic::db-client` as a SHARED IMPORTED target; `INTERFACE_LINK_LIBRARIES` brings in `gRPC::grpc++` and `protobuf::libprotobuf` automatically. No pkg-config fallback is shipped, so we do not need one.)
