Libxmtp 1.5.3 versions

[cameronvoell]

Add libxmtp 1.5.3-related dev versions by aliasing @xmtp/node-bindings@1.5.3-dev.5f2604f and @xmtp/node-sdk@4.3.0-dev.e66a716 in package.json and importing 4.3.0 client types in version-management/client-versions.ts

This change adds alias mappings for XMTP dev packages and imports the corresponding client types.

• Add alias mappings in package.json for @xmtp/node-bindings-1.5.3-dev.5f2604f -> npm:@xmtp/node-bindings@1.5.3-dev.5f2604f and @xmtp/node-sdk-4.3.0-dev.e66a716 -> npm:@xmtp/node-sdk@4.3.0-dev.e66a716
• Import Client as Client430, Conversation as Conversation430, Dm as Dm430, and Group as Group430 from @xmtp/node-sdk-4.3.0-dev.e66a716 in version-management/client-versions.ts
• Update yarn.lock to reflect dependency changes

📍Where to Start

Start with the alias entries in package.json, then review the new import block in version-management/client-versions.ts.
