GuildMemberInfo.cs:48-49 re-reads json["is_friend"] / json["is_friend_apply"]
UNGUARDED on top of the base-class UserInfoBase's guarded read. Our DTO had
them as int? with global WhenWritingNull → keys omitted → LitJson threw
KeyNotFoundException, crashing the client right after guild create.
Flip the fields to non-nullable int with JsonIgnoreCondition.Never so they
always ship, and wire a batched IFriendService.GetFriendRelationsAsync
lookup so the values are actually populated (single Contains-batched query
per relation table).

SendApplyAsync, ApproveApplyAsync, RejectApplyAsync, CancelApplyAsync,
RejectFriendAsync all implemented. 11 new tests appended; all 23 friend
tests pass, full suite 1182/1182 green.
GetFriendsAsync, GetReceiveAppliesAsync, GetSendAppliesAsync, GetPlayedTogetherAsync,
SearchAsync all implemented. LoadViewerProjectionAsync materialises the full Viewer
entity (with Include/ThenInclude for SelectedEmblem/Degree) then projects in-memory —
avoids the EF Core limitation where Include is silently ignored under Select.
FriendService + IPlayedTogetherWriter registered as Scoped in Program.cs.
12 read tests, all green; full suite 1171/1171 still passing.

Task 3: service contract (interface + DTOs) and FriendService skeleton.
All methods throw NotImplementedException; Tasks 4-6 fill in the logic.
