## Summary
Phase 3.3 of the message-interpolation cleanup. Eliminates the `rank.ToString().ToLower()` two-allocation pattern in ConPVP trophy-award messages.
- Adds `TrophyRank.LowerName()` extension returning a static lowercase string per enum value via switch expression.
- Updates 10 call sites across Tournament, KingOfTheHill, DoubleDom, CTF, BombingRun (2 each - cash and no-cash branches).
The handler now appends a static interned string directly into the packet buffer; no `ToString()` formatter and no `ToLower()` allocation per call. Source comment in BombingRun.cs ("There is no formatting flag for Lowercase, we may need a custom interface to get rid of it") is now resolved at the call-site level.
- [X] Caches DateTime.NowUtc on the game loop (not other threads)
- [X] Replaces all locations where it makes sense
- [X] Adds Min/Max for `IComparable` (TimeSpan, DateTimes, etc)
Closes#261
- [X] Fixes an issue where a buffer smaller than 8 bytes would not double with enough space in some cases.
- [X] Fixes an issue with dupe copying the savebuffer reference (ugh).
- [X] Streamlines the IGenericWriter API to use better generics.
- [X] Streamlines the IGenericReader API to use better generics.
- [X] Forces `tidying` of a List/HashSet to be done externally since Writers/Readers should not have side effects.
- [X] Fixes an issue where Tidying a list didn't TrimExcess, causing memory leaks.
- [X] Reverted the meaning of `World.Running` to specifically refer to any world state post world loading.
- NOTE: Do not use this if you want to block on world saves. Instead use checks against `WorldState.Saving` states.
- [X] Fixes an issue with serializing negative DateTime deltas.
- [X] Fixes a potential issue with serializing non-UTC DateTime.
