Converts BaseCreature's hand-written v22 serialization to codegen v23.
Nearly every field sits behind a [SaveFlag], so a creature matching its
defaults writes only [version int][ulong flags][default AI] - 13 bytes -
instead of ~236, and the writer's work is mostly branch-not-taken. With
500k-1M creatures in a world, this is the dominant slice of mobile save
freeze time and disk.
- Speeds serialize only when they differ from the creature's npc-speeds
values (GetSpeeds/GetMoveSpeeds on both the flag check and the load
default), so table edits now reach existing unmodified spawns on
restart, and former paragons (snapped back to table values) elide
fully. CurrentSpeed writes only when it differs from PassiveSpeed.
- The delete countdown is a [DeserializeTimer] field (anchored);
stabled/controlled pets never persist one, and the abandoned-pet
3-day fallback lives in AfterDeserialization for both load paths.
- SummonEnd stays anchored, written only while summoned.
- Old saves (v0-22) load through the retained legacy
Deserialize(reader, version), now assigning raw fields; the shared
post-load fixups (stat timers, AI creation, followers, animate-dead
registration, unsummon timer) moved to [AfterDeserialization].
- Side-effect setters became generated-field hooks (Team, Controlled,
Summoned, Loyalty clamp, resistance seeds, CurrentSpeed); properties
whose semantics the hooks cannot express stay hand-written as
[SerializableProperty] (ControlMaster/SummonMaster bracket the
assignment with follower bookkeeping, ControlOrder must run on equal
re-assignment, Tamable/IsParagon/move speeds have custom getters).
- CreatureDeathEvent/CreatureDeletedEvent moved to a CreatureEvents
host class: the events generator and the serialization generator each
emit a [GeneratedCode] partial for the declaring type, and the
attribute forbids duplicates (CS0579).
- m_ fields renamed to _camelCase.
Tests: new-format round trips (default and fully populated) with exact
byte consumption, back-to-back saves byte-identical, and a
byte-authentic fossilized v22 stream loading through the legacy path.
