Bump OTAPI to 3.3.12 for Terraria 1.4.5.7 support

[hufang360]

English

Updates TSAPI to OTAPI.Upcoming 3.3.12, which adds Terraria 1.4.5.7 support.

Changes:

• Bump OTAPI.Upcoming 3.3.11 → 3.3.12.
• NetHooks: Netplay.HasClients → Netplay.HasFullyConnectedClients; Netplay.StopListening() → Netplay.TcpListener?.StopListening() (the static method was removed in 1.4.5.7; ISocket.StopListening is kept).
• NpcHooks: NPC.StrikeNPC no longer takes a noEffect argument in 1.4.5.7; the public InvokeNpcStrike API is kept intact via a local variable.
• PacketTypes: packet 162 is now DamageNPCAck (new NPC-strike acknowledgement). The old ServerInfo/PlayerPlatformInfo members are kept as same-value aliases so existing plugins keep compiling.

Verified: dotnet build + tests pass; boot-tested with the vanilla 1.4.5.7 server – OTAPI reports Protocol v1.4.5.7 (325).

Changelog

• Update TSAPI to support Terraria 1.4.5.7 (OTAPI 3.3.12).

中文简介

升级 TSAPI 至 OTAPI.Upcoming 3.3.12（Terraria 1.4.5.7 适配版）。

改动：

• OTAPI.Upcoming 3.3.11 → 3.3.12。
• NetHooks：Netplay.HasClients → HasFullyConnectedClients；Netplay.StopListening() → Netplay.TcpListener?.StopListening()（1.4.5.7 移除该静态方法，ISocket.StopListening 仍保留）。
• NpcHooks：1.4.5.7 的 NPC.StrikeNPC 不再有 noEffect 参数，以局部变量保持公共 InvokeNpcStrike API 不变。
• PacketTypes：162 号包现在是 DamageNPCAck（新增的 NPC 打击确认包）；保留旧 ServerInfo/PlayerPlatformInfo 为同值别名，避免旧插件编译失败。

已验证：构建 + 单测通过；用原版 1.4.5.7 服务器实测可启动（OTAPI 报告 Protocol v1.4.5.7 (325)）。

Changelog

• TSAPI 升级以支持 Terraria 1.4.5.7（OTAPI 3.3.12）。

Closing this in favour of #283, which carries the same changes and is under review.

I've verified the port against OTAPI 3.3.13 (TSAPI net9 build clean; TShock boots with the vanilla 1.4.5.7 server, Protocol v1.4.5.7 (325)). Details and next steps are in my comment on #283.

Thanks!
